-Basic Installation
-==================
-
- These are generic installation instructions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. While running, it prints some
- messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. Run `./configure --help'
-for details on some of the pertinent environment variables.
-
- You can give `configure' initial values for variables by setting
-them in the environment. You can do that on the command line like this:
-
- ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
- *Note Environment Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory. After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
- By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc. You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of host the package
-will run on. Usually `configure' can figure that out, but if it prints
-a message saying it cannot guess the host type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS
- KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the host
-platform (i.e., that on which the generated programs will eventually be
-run) with `--host=TYPE'. In this case, you should also specify the
-build platform with `--build=TYPE', because, in this case, it may not
-be possible to guess the build platform (it sometimes involves
-compiling and running simple test programs, and this can't be done if
-the compiler is a cross compiler).
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Environment Variables
-=====================
-
- Variables not defined in a site shell script can be set in the
-environment passed to configure. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-`configure' Invocation
-======================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

+Major changes in Gzip 1.3.6 (2006-11-20)
+
+* Fix some race conditions in setting file time stamps, permissions, and owner.
+* Fix some race conditions in signal handling.
+* When gzip exits due to a signal, it exits with the signal's status, not 1.
+* gzip now restores file time stamps to the resolution supported by the
+ time-setting primitives of the operating system, typically 1 microsecond.
+ Formerly it restored them only to the nearest second.
+* gzip -r no longer attempts to reset the last-access times of directories
+ it reads, as this messes up when other processes are reading the directories.
+* The options --version and --help now work on all gzip-installed executables,
+ and now use a format similar to other GNU programs.
+* The manual is now distributed under the terms of the GNU Free
+ Documentation License without invariant sections or cover texts.
+* Port to current versions of Autoconf, Automake, and Gnulib.
Major changes from 1.3.4 to 1.3.5
* gzip now removes any output symlink before writing output file.
Major changes from 1.0.3 to 1.0.4.
* Added optimized asm version for 68020.
* Add support for DJGPP.
-
+
* Add support for the Atari ST.
* Added zforce to rename gzip'ed files with truncated names.
* Do not install with name uncompress (some systems rely on the
* Accept gzcat in addition to zcat for people having /usr/bin before
/usr/local/bin in their path.

+This is the file README for the gzip distribution.
gzip (GNU zip) is a compression utility designed to be a replacement
for 'compress'. Its main advantages over compress are much better
authors of these two programs work closely together in the info-zip
team. zip and unzip are not associated with the GNU project.
See http://www.cdrom.com/pub/infozip/ for more about zip and unzip.

+
+These notes intend to help people working on the CVS version of
+this package.
+
+* Requirements
+
+Only the sources are installed in the CVS repository (to ease the
+maintenance, merges etc.), therefore you will have to get the latest
+stable versions of the maintainer tools we depend upon, including:
+
+- Automake <http://www.gnu.org/software/automake/>
+- Autoconf <http://www.gnu.org/software/autoconf/>
+- Tar <http://www.gnu.org/software/tar/>
+- Wget <http://www.gnu.org/software/wget/>
+
+Valgrind <http://valgrind.org/> is also highly recommended, if
+Valgrind supports your architecture.
+
+Only building the initial full source tree will be a bit painful,
+later, a plain `cvs update -P && make' should be sufficient.
+
+* First CVS checkout
+
+Obviously, if you are reading these notes, you did manage to check out
+this package from CVS. The next step is to get other files needed to
+build, which are extracted from other source packages:
+
+ $ ./bootstrap
+
+And there you are! Just
+
+ $ ./configure
+ $ make
+ $ make check
+
+At this point, there should be no difference between your local copy,
+and the CVS master copy:
+
+ $ cvs diff
+
+should output no difference.
+
+Enjoy!

-Some of the planned features include:
+- Separate out the shell scripts like gzexe into a new little package;

- Internationalize by using gettext and setlocale.
'compress' currently handles better than gzip.

-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --disable-dependency-tracking Speeds up one-time builds
- --enable-dependency-tracking Do not reject slow dependency extractors
- --disable-largefile omit support for large files
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
- headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to <bug-gzip@gnu.org>.

+@chapter Overview
+@cindex overview
+
+@code{gzip} reduces the size of the named files using Lempel-Ziv coding
+(LZ77). Whenever possible, each file is replaced by one with the
+extension @samp{.gz}, while keeping the same ownership modes, access and
+modification times. (The default extension is @samp{-gz} for VMS,
+@samp{z} for MSDOS, OS/2 FAT and Atari.) If no files are specified or
+if a file name is "-", the standard input is compressed to the standard
+output. @code{gzip} will only attempt to compress regular files. In
+particular, it will ignore symbolic links.
+
+If the new file name is too long for its file system, @code{gzip}
+truncates it. @code{gzip} attempts to truncate only the parts of the
+file name longer than 3 characters. (A part is delimited by dots.) If
+the name consists of small parts only, the longest parts are truncated.
+For example, if file names are limited to 14 characters, gzip.msdos.exe
+is compressed to gzi.msd.exe.gz. Names are not truncated on systems
+which do not have a limit on file name length.
+
+By default, @code{gzip} keeps the original file name and timestamp in
+the compressed file. These are used when decompressing the file with the
+@samp{-N} option. This is useful when the compressed file name was
+truncated or when the time stamp was not preserved after a file
+transfer.
+
+Compressed files can be restored to their original form using @samp{gzip -d}
+or @code{gunzip} or @code{zcat}. If the original name saved in the
+compressed file is not suitable for its file system, a new name is
+constructed from the original one to make it legal.
+
+@code{gunzip} takes a list of files on its command line and replaces
+each file whose name ends with @samp{.gz}, @samp{.z}, @samp{.Z},
+@samp{-gz}, @samp{-z} or @samp{_z} and which begins with the correct
+magic number with an uncompressed file without the original extension.
+@code{gunzip} also recognizes the special extensions @samp{.tgz} and
+@samp{.taz} as shorthands for @samp{.tar.gz} and @samp{.tar.Z}
+respectively. When compressing, @code{gzip} uses the @samp{.tgz}
+extension if necessary instead of truncating a file with a @samp{.tar}
+extension.
+
+@code{gunzip} can currently decompress files created by @code{gzip},
+@code{zip}, @code{compress} or @code{pack}. The detection of the input
+format is automatic. When using the first two formats, @code{gunzip}
+checks a 32 bit CRC (cyclic redundancy check). For @code{pack},
+@code{gunzip} checks the uncompressed length. The @code{compress} format
+was not designed to allow consistency checks. However @code{gunzip} is
+sometimes able to detect a bad @samp{.Z} file. If you get an error when
+uncompressing a @samp{.Z} file, do not assume that the @samp{.Z} file is
+correct simply because the standard @code{uncompress} does not complain.
+This generally means that the standard @code{uncompress} does not check
+its input, and happily generates garbage output. The SCO @samp{compress
+-H} format (@code{lzh} compression method) does not include a CRC but
+also allows some consistency checks.
+
+Files created by @code{zip} can be uncompressed by @code{gzip} only if
+they have a single member compressed with the 'deflation' method. This
+feature is only intended to help conversion of @code{tar.zip} files to
+the @code{tar.gz} format. To extract a @code{zip} file with a single
+member, use a command like @samp{gunzip <foo.zip} or @samp{gunzip -S
+.zip foo.zip}. To extract @code{zip} files with several
+members, use @code{unzip} instead of @code{gunzip}.
+
+@code{zcat} is identical to @samp{gunzip -c}. @code{zcat}
+uncompresses either a list of files on the command line or its standard
+input and writes the uncompressed data on standard output. @code{zcat}
+will uncompress files that have the correct magic number whether they
+have a @samp{.gz} suffix or not.
+
+@code{gzip} uses the Lempel-Ziv algorithm used in @code{zip} and PKZIP.
+The amount of compression obtained depends on the size of the input and
+the distribution of common substrings. Typically, text such as source
+code or English is reduced by 60-70%. Compression is generally much
+better than that achieved by LZW (as used in @code{compress}), Huffman
+coding (as used in @code{pack}), or adaptive Huffman coding
+(@code{compact}).
+
+Compression is always performed, even if the compressed file is slightly
+larger than the original. The worst case expansion is a few bytes for
+the @code{gzip} file header, plus 5 bytes every 32K block, or an expansion
+ratio of 0.015% for large files. Note that the actual number of used
+disk blocks almost never increases. @code{gzip} preserves the mode,
+ownership and timestamps of files when compressing or decompressing.
+
+The @code{gzip} file format is specified in P. Deutsch, @sc{gzip} file
+format specification version 4.3,
+@uref{ftp://ftp.isi.edu/in-notes/rfc1952.txt, Internet RFC 1952} (May
+1996). The @code{zip} deflation format is specified in P. Deutsch,
+@sc{deflate} Compressed Data Format Specification version 1.3,
+@uref{ftp://ftp.isi.edu/in-notes/rfc1951.txt, Internet RFC 1951} (May
+1996).

+@cindex sample
+
+Here are some realistic examples of running @code{gzip}.
+
+This is the output of the command @samp{gzip -h}:
+
+@example
+gzip @var{version-number}
+usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...]
+ -c --stdout write on standard output, keep original files unchanged
+ -d --decompress decompress
+ -f --force force overwrite of output file and compress links

+ -L --license display software license
+ -n --no-name do not save or restore the original name and time stamp
+ -N --name save or restore the original name and time stamp
+ -q --quiet suppress all warnings
+ -r --recursive operate recursively on directories
+ -S .suf --suffix .suf use suffix .suf on compressed files
+ -t --test test compressed file integrity
+ -v --verbose verbose mode
+ -V --version display version number
+ -1 --fast compress faster
+ -9 --best compress better
+ file... files to (de)compress. If none given, use standard input.
+Report bugs to <bug-gzip@@gnu.org>.
+@end example
+
+This is the output of the command @samp{gzip -v texinfo.tex}:
+
+@example
+texinfo.tex: 69.7% -- replaced with texinfo.tex.gz
+@end example
+
+The following command will find all @code{gzip} files in the current
+directory and subdirectories, and extract them in place without
+destroying the original:
+
+@example
+find . -name '*.gz' -print | sed 's/^\(.*\)[.]gz$/gunzip < "&" > "\1"/' | sh
+@end example
+
+@node Invoking gzip, Advanced usage, Sample, Top
+@chapter Invoking @code{gzip}
+@cindex invoking
+@cindex options
+
+The format for running the @code{gzip} program is:
+
+@example
+gzip @var{option} @dots{}
+@end example
+
+@code{gzip} supports the following options:
+
+@table @samp
+@item --stdout
+@itemx --to-stdout
+@itemx -c
+Write output on standard output; keep original files unchanged.
+If there are several input files, the output consists of a sequence of
+independently compressed members. To obtain better compression,
+concatenate all input files before compressing them.
+
+@item --decompress
+@itemx --uncompress
+@itemx -d
+Decompress.
+
+@item --force
+@itemx -f
+Force compression or decompression even if the file has multiple links
+or the corresponding file already exists, or if the compressed data
+is read from or written to a terminal. If the input data is not in
+a format recognized by @code{gzip}, and if the option @samp{--stdout} is also
+given, copy the input data without change to the standard output: let
+@code{zcat} behave as @code{cat}. If @samp{-f} is not given, and
+when not running in the background, @code{gzip} prompts to verify
+whether an existing file should be overwritten.
+
+@item --help
+@itemx -h
+Print an informative help message describing the options then quit.
+
+@item --list
+@itemx -l
+For each compressed file, list the following fields:
+
+@example
+compressed size: size of the compressed file
+uncompressed size: size of the uncompressed file
+ratio: compression ratio (0.0% if unknown)
+uncompressed_name: name of the uncompressed file
+@end example
+
+The uncompressed size is given as @samp{-1} for files not in @code{gzip}
+format, such as compressed @samp{.Z} files. To get the uncompressed size for
+such a file, you can use:
+
+@example
+zcat file.Z | wc -c
+@end example
+
+In combination with the @samp{--verbose} option, the following fields are also
+displayed:
+
+@example
+method: compression method (deflate,compress,lzh,pack)
+crc: the 32-bit CRC of the uncompressed data
+date & time: time stamp for the uncompressed file
+@end example
+
+The crc is given as ffffffff for a file not in gzip format.
+
+With @samp{--verbose}, the size totals and compression ratio for all files
+is also displayed, unless some sizes are unknown. With @samp{--quiet},
+the title and totals lines are not displayed.
+
+The @code{gzip} format represents the the input size modulo
+@math{2^32}, so the uncompressed size and compression ratio are listed
+incorrectly for uncompressed files 4 GB and larger. To work around
+this problem, you can use the following command to discover a large
+uncompressed file's true size:
+
+@example
+zcat file.gz | wc -c
+@end example
+
+@item --license
+@itemx -L
+Display the @code{gzip} license then quit.
+
+@item --no-name
+@itemx -n
+When compressing, do not save the original file name and time stamp by
+default. (The original name is always saved if the name had to be
+truncated.) When decompressing, do not restore the original file name
+if present (remove only the @code{gzip}
+suffix from the compressed file name) and do not restore the original
+time stamp if present (copy it from the compressed file). This option
+is the default when decompressing.
+
+@item --name
+@itemx -N
+When compressing, always save the original file name and time stamp; this
+is the default. When decompressing, restore the original file name and
+time stamp if present. This option is useful on systems which have
+a limit on file name length or when the time stamp has been lost after
+a file transfer.
+
+@item --quiet
+@itemx -q
+Suppress all warning messages.
+
+@item --recursive
+@itemx -r
+Travel the directory structure recursively. If any of the file names
+specified on the command line are directories, @code{gzip} will descend
+into the directory and compress all the files it finds there (or
+decompress them in the case of @code{gunzip}).
+
+@item --suffix @var{suf}
+@itemx -S @var{suf}
+Use suffix @samp{@var{suf}} instead of @samp{.gz}. Any suffix can be
+given, but suffixes other than @samp{.z} and @samp{.gz} should be
+avoided to avoid confusion when files are transferred to other systems.
+A null suffix forces gunzip to try decompression on all given files
+regardless of suffix, as in:
+
+@example
+gunzip -S "" * (*.* for MSDOS)
+@end example
+
+Previous versions of gzip used the @samp{.z} suffix. This was changed to
+avoid a conflict with @code{pack}.
+
+@item --test
+@itemx -t
+Test. Check the compressed file integrity.
+
+@item --verbose
+@itemx -v
+Verbose. Display the name and percentage reduction for each file compressed.
+
+@item --version
+@itemx -V
+Version. Display the version number and compilation options, then quit.
+
+@item --fast
+@itemx --best
+@itemx -@var{n}
+Regulate the speed of compression using the specified digit @var{n},
+where @samp{-1} or @samp{--fast} indicates the fastest compression
+method (less compression) and @samp{--best} or @samp{-9} indicates the
+slowest compression method (optimal compression). The default
+compression level is @samp{-6} (that is, biased towards high compression at
+expense of speed).
+@end table
+
+@node Advanced usage, Environment, Invoking gzip, Top
+@chapter Advanced usage
+@cindex concatenated files
+
+Multiple compressed files can be concatenated. In this case,
+@code{gunzip} will extract all members at once. If one member is
+damaged, other members might still be recovered after removal of the
+damaged member. Better compression can be usually obtained if all
+members are decompressed and then recompressed in a single step.
+
+This is an example of concatenating @code{gzip} files:
+
+@example
+gzip -c file1 > foo.gz
+gzip -c file2 >> foo.gz
+@end example
+
+Then
+
+@example
+gunzip -c foo
+@end example
+
+is equivalent to
+
+@example
+cat file1 file2
+@end example
+
+In case of damage to one member of a @samp{.gz} file, other members can
+still be recovered (if the damaged member is removed). However,
+you can get better compression by compressing all members at once:
+
+@example
+cat file1 file2 | gzip > foo.gz
+@end example
+
+compresses better than
+
+@example
+gzip -c file1 file2 > foo.gz
+@end example
+
+If you want to recompress concatenated files to get better compression, do:
+
+@example
+zcat old.gz | gzip > new.gz
+@end example
+
+If a compressed file consists of several members, the uncompressed
+size and CRC reported by the @samp{--list} option applies to the last member
+only. If you need the uncompressed size for all members, you can use:
+
+@example
+zcat file.gz | wc -c
+@end example
+
+If you wish to create a single archive file with multiple members so
+that members can later be extracted independently, use an archiver such
+as @code{tar} or @code{zip}. GNU @code{tar} supports the @samp{-z}
+option to invoke @code{gzip} transparently. @code{gzip} is designed as a
+complement to @code{tar}, not as a replacement.
+
+@node Environment, Tapes, Advanced usage, Top
+@chapter Environment
+@cindex Environment
+
+The environment variable @code{GZIP} can hold a set of default options for
+@code{gzip}. These options are interpreted first and can be overwritten by
+explicit command line parameters. For example:
+
+@example
+for sh: GZIP="-8v --name"; export GZIP
+for csh: setenv GZIP "-8v --name"
+for MSDOS: set GZIP=-8v --name
+@end example
+
+On Vax/VMS, the name of the environment variable is @code{GZIP_OPT}, to
+avoid a conflict with the symbol set for invocation of the program.
+
+@node Tapes, Problems, Environment, Top
+@chapter Using @code{gzip} on tapes
+@cindex tapes
+
+When writing compressed data to a tape, it is generally necessary to pad
+the output with zeroes up to a block boundary. When the data is read and
+the whole block is passed to @code{gunzip} for decompression,
+@code{gunzip} detects that there is extra trailing garbage after the
+compressed data and emits a warning by default if the garbage contains
+nonzero bytes. You have to use the
+@samp{--quiet} option to suppress the warning. This option can be set in the
+@code{GZIP} environment variable, as in:
+
+@example
+for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0
+for csh: (setenv GZIP "-q"; tar -xfz --block-compress /dev/rst0)
+@end example
+
+In the above example, @code{gzip} is invoked implicitly by the @samp{-z}
+option of GNU @code{tar}. Make sure that the same block size (@samp{-b}
+option of @code{tar}) is used for reading and writing compressed data on
+tapes. (This example assumes you are using the GNU version of
+@code{tar}.)

-PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-written document @dfn{free} in the sense of freedom: to assure everyone
-the effective freedom to copy and redistribute it, with or without
-modifying it, either commercially or noncommercially. Secondarily,
-this License preserves for the author and publisher a way to get
-credit for their work, while not being considered responsible for
-modifications made by others.
-
-This License is a kind of ``copyleft'', which means that derivative
-works of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does. But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book. We recommend this License
-principally for works whose purpose is instruction or reference.
-
-@item
-APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work that contains a
-notice placed by the copyright holder saying it can be distributed
-under the terms of this License. The ``Document'', below, refers to any
-such manual or work. Any member of the public is a licensee, and is
-addressed as ``you''.
-
-A ``Modified Version'' of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A ``Secondary Section'' is a named appendix or a front-matter section of
-the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall subject
-(or to related matters) and contains nothing that could fall directly
-within that overall subject. (For example, if the Document is in part a
-textbook of mathematics, a Secondary Section may not explain any
-mathematics.) The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The ``Invariant Sections'' are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License.
-
-The ``Cover Texts'' are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License.
-
-A ``Transparent'' copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, whose contents can be viewed and edited directly and
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters. A copy made in an otherwise Transparent file
-format whose markup has been designed to thwart or discourage
-subsequent modification by readers is not Transparent. A copy that is
-not ``Transparent'' is called ``Opaque''.
-
-Examples of suitable formats for Transparent copies include plain
-@sc{ascii} without markup, Texinfo input format, La@TeX{} input format,
-@acronym{SGML} or @acronym{XML} using a publicly available
-@acronym{DTD}, and standard-conforming simple @acronym{HTML} designed
-for human modification. Opaque formats include PostScript,
-@acronym{PDF}, proprietary formats that can be read and edited only by
-proprietary word processors, @acronym{SGML} or @acronym{XML} for which
-the @acronym{DTD} and/or processing tools are not generally available,
-and the machine-generated @acronym{HTML} produced by some word
-processors for output purposes only.
-
-The ``Title Page'' means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page. For works in
-formats which do not have any title page as such, ``Title Page'' means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.

-VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License. You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-@item
-COPYING IN QUANTITY
-
-If you publish printed copies of the Document numbering more than 100,
-and the Document's license notice requires Cover Texts, you must enclose
-the copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover. Both covers must also clearly and legibly identify
-you as the publisher of these copies. The front cover must present
-the full title with all words of the title equally prominent and
-visible. You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a publicly-accessible computer-network location containing a complete
-Transparent copy of the Document, free of added material, which the
-general network-using public has access to download anonymously at no
-charge using public-standard network protocols. If you use the latter
-option, you must take reasonably prudent steps, when you begin
-distribution of Opaque copies in quantity, to ensure that this
-Transparent copy will remain thus accessible at the stated location
-until at least one year after the last time you distribute an Opaque
-copy (directly or through your agents or retailers) of that edition to
-the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-
-@item
-MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it. In addition, you must do these things in the Modified Version:
-
-@enumerate A
-@item
-Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document). You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-@item
-List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has less than five).
-
-@item
-State on the Title page the name of the publisher of the
-Modified Version, as the publisher.

-@item
-AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, does not as a whole count as a Modified Version
-of the Document, provided no compilation copyright is claimed for the
-compilation. Such a compilation is called an ``aggregate'', and this
-License does not apply to the other self-contained works thus compiled
-with the Document, on account of their being thus compiled, if they
-are not themselves derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one quarter
-of the entire aggregate, the Document's Cover Texts may be placed on
-covers that surround only the Document within the aggregate.
-Otherwise they must appear on covers around the whole aggregate.
-
-@item
-TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License provided that you also include the
-original English version of this License. In case of a disagreement
-between the translation and the original English version of this
-License, the original English version will prevail.

-@item
-TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document except
-as expressly provided for under this License. Any other attempt to
-copy, modify, sublicense or distribute the Document is void, and will
-automatically terminate your rights under this License. However,
-parties who have received copies, or rights, from you under this
-License will not have their licenses terminated so long as such
-parties remain in full compliance.

- given in OPTSTRING.
-
- If an element of ARGV starts with '-', and is not exactly "-" or "--",
- then it is an option element. The characters of this element
- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns -1.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of
- handling the non-option ARGV-elements.
- See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible

-NAME
- gzip, gunzip, zcat - compress or expand files
-
-SYNOPSIS
- gzip [ -acdfhlLnNrtvV19 ] [-S suffix] [ name ... ]
- gunzip [ -acfhlLnNrtvV ] [-S suffix] [ name ... ]
- zcat [ -fhLV ] [ name ... ]
-
-DESCRIPTION
- Gzip reduces the size of the named files using Lempel-Ziv
- coding (LZ77). Whenever possible, each file is replaced by
- one with the extension .gz, while keeping the same ownership
- modes, access and modification times. (The default exten-
- sion is -gz for VMS, z for MSDOS, OS/2 FAT, Windows NT FAT
- and Atari.) If no files are specified, or if a file name is
- "-", the standard input is compressed to the standard out-
- put. Gzip will only attempt to compress regular files. In
- particular, it will ignore symbolic links.
-
- If the compressed file name is too long for its file system,
- gzip truncates it. Gzip attempts to truncate only the parts
- of the file name longer than 3 characters. (A part is
- delimited by dots.) If the name consists of small parts
- only, the longest parts are truncated. For example, if file
- names are limited to 14 characters, gzip.msdos.exe is com-
- pressed to gzi.msd.exe.gz. Names are not truncated on sys-
- tems which do not have a limit on file name length.
-
- By default, gzip keeps the original file name and timestamp
- in the compressed file. These are used when decompressing
- the file with the -N option. This is useful when the com-
- pressed file name was truncated or when the time stamp was
- not preserved after a file transfer.
-
- Compressed files can be restored to their original form
- using gzip -d or gunzip or zcat. If the original name saved
- in the compressed file is not suitable for its file system,
- a new name is constructed from the original one to make it
- legal.
-
- gunzip takes a list of files on its command line and
- replaces each file whose name ends with .gz, -gz, .z, -z, _z
- or .Z and which begins with the correct magic number with an
- uncompressed file without the original extension. gunzip
- also recognizes the special extensions .tgz and .taz as
- shorthands for .tar.gz and .tar.Z respectively. When com-
- pressing, gzip uses the .tgz extension if necessary instead
- of truncating a file with a .tar extension.
-
- gunzip can currently decompress files created by gzip, zip,
- compress, compress -H or pack. The detection of the input
- format is automatic. When using the first two formats,
-
-SunOS 5.8 Last change: local 1
-
-User Commands GZIP(1)
-
- gunzip checks a 32 bit CRC. For pack, gunzip checks the
- uncompressed length. The standard compress format was not
- designed to allow consistency checks. However gunzip is
- sometimes able to detect a bad .Z file. If you get an error
- when uncompressing a .Z file, do not assume that the .Z file
- is correct simply because the standard uncompress does not
- complain. This generally means that the standard uncompress
- does not check its input, and happily generates garbage out-
- put. The SCO compress -H format (lzh compression method)
- does not include a CRC but also allows some consistency
- checks.
-
- Files created by zip can be uncompressed by gzip only if
- they have a single member compressed with the 'deflation'
- method. This feature is only intended to help conversion of
- tar.zip files to the tar.gz format. To extract a zip file
- with a single member, use a command like gunzip <foo.zip or
- gunzip -S .zip foo.zip. To extract zip files with several
- members, use unzip instead of gunzip.
-
- zcat is identical to gunzip -c. (On some systems, zcat may
- be installed as gzcat to preserve the original link to com-
- press.) zcat uncompresses either a list of files on the
- command line or its standard input and writes the uncom-
- pressed data on standard output. zcat will uncompress files
- that have the correct magic number whether they have a .gz
- suffix or not.
-
- Gzip uses the Lempel-Ziv algorithm used in zip and PKZIP.
- The amount of compression obtained depends on the size of
- the input and the distribution of common substrings. Typi-
- cally, text such as source code or English is reduced by
- 60-70%. Compression is generally much better than that
- achieved by LZW (as used in compress), Huffman coding (as
- used in pack), or adaptive Huffman coding (compact).
-
- Compression is always performed, even if the compressed file
- is slightly larger than the original. The worst case expan-
- sion is a few bytes for the gzip file header, plus 5 bytes
- every 32K block, or an expansion ratio of 0.015% for large
- files. Note that the actual number of used disk blocks
- almost never increases. gzip preserves the mode, ownership
- and timestamps of files when compressing or decompressing.
-
- The gzip file format is specified in P. Deutsch, GZIP file
- format specification version 4.3, <ftp://ftp.isi.edu/in-
- notes/rfc1952.txt>, Internet RFC 1952 (May 1996). The zip
- deflation format is specified in P. Deutsch, DEFLATE Com-
- pressed Data Format Specification version 1.3,
- <ftp://ftp.isi.edu/in-notes/rfc1951.txt>, Internet RFC 1951
- (May 1996).

-OPTIONS
- -a --ascii
- Ascii text mode: convert end-of-lines using local con-
- ventions. This option is supported only on some non-
- Unix systems. For MSDOS, CR LF is converted to LF when
- compressing, and LF is converted to CR LF when decom-
- pressing.
-
- -c --stdout --to-stdout
- Write output on standard output; keep original files
- unchanged. If there are several input files, the out-
- put consists of a sequence of independently compressed
- members. To obtain better compression, concatenate all
- input files before compressing them.
-
- -d --decompress --uncompress
- Decompress.

- -f --force
- Force compression or decompression even if the file has
- multiple links or the corresponding file already
- exists, or if the compressed data is read from or writ-
- ten to a terminal. If the input data is not in a format
- recognized by gzip, and if the option --stdout is also
- given, copy the input data without change to the stan-
- dard ouput: let zcat behave as cat. If -f is not
- given, and when not running in the background, gzip
- prompts to verify whether an existing file should be
- overwritten.
-
- -h --help
- Display a help screen and quit.
-
- -l --list
- For each compressed file, list the following fields:
-
- compressed size: size of the compressed file
- uncompressed size: size of the uncompressed file
- ratio: compression ratio (0.0% if unknown)
- uncompressed_name: name of the uncompressed file
-
- The uncompressed size is given as -1 for files not in
- gzip format, such as compressed .Z files. To get the
- uncompressed size for such a file, you can use:
-
- zcat file.Z | wc -c
-
- In combination with the --verbose option, the following
- fields are also displayed:
-
- method: compression method
- crc: the 32-bit CRC of the uncompressed data
-
-SunOS 5.8 Last change: local 3
-
-User Commands GZIP(1)
-
- date & time: time stamp for the uncompressed file
-
- The compression methods currently supported are
- deflate, compress, lzh (SCO compress -H) and pack. The
- crc is given as ffffffff for a file not in gzip format.
-
- With --name, the uncompressed name, date and time are
- those stored within the compress file if present.
-
- With --verbose, the size totals and compression ratio
- for all files is also displayed, unless some sizes are
- unknown. With --quiet, the title and totals lines are
- not displayed.
-
- -L --license
- Display the gzip license and quit.
-
- -n --no-name
- When compressing, do not save the original file name
- and time stamp by default. (The original name is always
- saved if the name had to be truncated.) When decom-
- pressing, do not restore the original file name if pre-
- sent (remove only the gzip suffix from the compressed
- file name) and do not restore the original time stamp
- if present (copy it from the compressed file). This
- option is the default when decompressing.
-
- -N --name
- When compressing, always save the original file name
- and time stamp; this is the default. When decompress-
- ing, restore the original file name and time stamp if
- present. This option is useful on systems which have a
- limit on file name length or when the time stamp has
- been lost after a file transfer.
-
- -q --quiet
- Suppress all warnings.
-
- -r --recursive
- Travel the directory structure recursively. If any of
- the file names specified on the command line are direc-
- tories, gzip will descend into the directory and com-
- press all the files it finds there (or decompress them
- in the case of gunzip ).
-
- -S .suf --suffix .suf
- Use suffix .suf instead of .gz. Any suffix can be
- given, but suffixes other than .z and .gz should be
- avoided to avoid confusion when files are transferred
- to other systems. A null suffix forces gunzip to try
- decompression on all given files regardless of suffix,
- as in:
-
-SunOS 5.8 Last change: local 4
-
-User Commands GZIP(1)
-
- gunzip -S "" * (*.* for MSDOS)
-
- Previous versions of gzip used the .z suffix. This was
- changed to avoid a conflict with pack(1).
-
- -t --test
- Test. Check the compressed file integrity.
-
- -v --verbose
- Verbose. Display the name and percentage reduction for
- each file compressed or decompressed.
-
- -V --version
- Version. Display the version number and compilation
- options then quit.
-
- -# --fast --best
- Regulate the speed of compression using the specified
- digit #, where -1 or --fast indicates the fastest com-
- pression method (less compression) and -9 or --best
- indicates the slowest compression method (best compres-
- sion). The default compression level is -6 (that is,
- biased towards high compression at expense of speed).
-
-ADVANCED USAGE
- Multiple compressed files can be concatenated. In this case,
- gunzip will extract all members at once. For example:
-
- gzip -c file1 > foo.gz
- gzip -c file2 >> foo.gz
-
- Then
-
- gunzip -c foo
-
- is equivalent to
-
- cat file1 file2
-
- In case of damage to one member of a .gz file, other members
- can still be recovered (if the damaged member is removed).
- However, you can get better compression by compressing all
- members at once:
-
- cat file1 file2 | gzip > foo.gz
-
- compresses better than
-
- gzip -c file1 file2 > foo.gz
-
- If you want to recompress concatenated files to get better
- compression, do:
-
-SunOS 5.8 Last change: local 5
-
-User Commands GZIP(1)
-
- gzip -cd old.gz | gzip > new.gz
-
- If a compressed file consists of several members, the uncom-
- pressed size and CRC reported by the --list option applies
- to the last member only. If you need the uncompressed size
- for all members, you can use:
-
- gzip -cd file.gz | wc -c
-
- If you wish to create a single archive file with multiple
- members so that members can later be extracted indepen-
- dently, use an archiver such as tar or zip. GNU tar supports
- the -z option to invoke gzip transparently. gzip is designed
- as a complement to tar, not as a replacement.
-
-ENVIRONMENT
- The environment variable GZIP can hold a set of default
- options for gzip. These options are interpreted first and
- can be overwritten by explicit command line parameters. For
- example:
- for sh: GZIP="-8v --name"; export GZIP
- for csh: setenv GZIP "-8v --name"
- for MSDOS: set GZIP=-8v --name
-
- On Vax/VMS, the name of the environment variable is
- GZIP_OPT, to avoid a conflict with the symbol set for invo-
- cation of the program.

-
- the point of failure can be recovered using
-
- zcat file > recover
-
- file: compressed with xx bits, can only handle yy bits
- File was compressed (using LZW) by a program that could
- deal with more bits than the decompress code on this
- machine. Recompress the file with gzip, which com-
- presses better and uses less memory.
-
- file: already has .gz suffix -- no change
- The file is assumed to be already compressed. Rename
- the file and try again.
-
- file already exists; do you wish to overwrite (y or n)?
- Respond "y" if you want the output file to be replaced;
- "n" if not.
-
- gunzip: corrupt input
- A SIGSEGV violation was detected which usually means
- that the input file has been corrupted.
-
- xx.x% Percentage of the input saved by compression.
- (Relevant only for -v and -l.)
-
- -- not a regular file or directory: ignored
- When the input file is not a regular file or directory,
- (e.g. a symbolic link, socket, FIFO, device file), it
- is left unaltered.
-
- -- has xx other links: unchanged
- The input file has links; it is left unchanged. See
- ln(1) for more information. Use the -f flag to force
- compression of multiply-linked files.
-
-CAVEATS
- When writing compressed data to a tape, it is generally nec-
- essary to pad the output with zeroes up to a block boundary.
- When the data is read and the whole block is passed to gun-
- zip for decompression, gunzip detects that there is extra
- trailing garbage after the compressed data and emits a warn-
- ing by default. You have to use the --quiet option to sup-
- press the warning. This option can be set in the GZIP envi-
- ronment variable as in:
- for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0
- for csh: (setenv GZIP -q; tar -xfz --block-compr /dev/rst0
-
- In the above example, gzip is invoked implicitly by the -z
- option of GNU tar. Make sure that the same block size (-b
- option of tar) is used for reading and writing compressed
- data on tapes. (This example assumes you are using the GNU
- version of tar.)

-
-BUGS
- The gzip format represents the the input size modulo 2^32,
- so the --list option reports incorrect uncompressed sizes
- and compression ratios for uncompressed files 4 GB and
- larger. To work around this problem, you can use the fol-
- lowing command to discover a large uncompressed file's true
- size:
-
- zcat file.gz | wc -c
-
- The --list option reports sizes as -1 and crc as ffffffff if
- the compressed file is on a non seekable media.
-
- In some rare cases, the --best option gives worse compres-
- sion than the default compression level (-6). On some highly
- redundant files, compress compresses better than gzip.

-Overview
-********
-
- `gzip' reduces the size of the named files using Lempel-Ziv coding
-(LZ77). Whenever possible, each file is replaced by one with the
-extension `.gz', while keeping the same ownership modes, access and
-modification times. (The default extension is `-gz' for VMS, `z' for
-MSDOS, OS/2 FAT and Atari.) If no files are specified or if a file
-name is "-", the standard input is compressed to the standard output.
-`gzip' will only attempt to compress regular files. In particular, it
-will ignore symbolic links.
-
- If the new file name is too long for its file system, `gzip'
-truncates it. `gzip' attempts to truncate only the parts of the file
-name longer than 3 characters. (A part is delimited by dots.) If the
-name consists of small parts only, the longest parts are truncated.
-For example, if file names are limited to 14 characters, gzip.msdos.exe
-is compressed to gzi.msd.exe.gz. Names are not truncated on systems
-which do not have a limit on file name length.
-
- By default, `gzip' keeps the original file name and timestamp in the
-compressed file. These are used when decompressing the file with the
-`-N' option. This is useful when the compressed file name was truncated
-or when the time stamp was not preserved after a file transfer.
-
- Compressed files can be restored to their original form using `gzip
--d' or `gunzip' or `zcat'. If the original name saved in the
-compressed file is not suitable for its file system, a new name is
-constructed from the original one to make it legal.
-
- `gunzip' takes a list of files on its command line and replaces each
-file whose name ends with `.gz', `.z', `.Z', `-gz', `-z' or `_z' and
-which begins with the correct magic number with an uncompressed file
-without the original extension. `gunzip' also recognizes the special
-extensions `.tgz' and `.taz' as shorthands for `.tar.gz' and `.tar.Z'
-respectively. When compressing, `gzip' uses the `.tgz' extension if
-necessary instead of truncating a file with a `.tar' extension.
-
- `gunzip' can currently decompress files created by `gzip', `zip',
-`compress' or `pack'. The detection of the input format is automatic.
-When using the first two formats, `gunzip' checks a 32 bit CRC (cyclic
-redundancy check). For `pack', `gunzip' checks the uncompressed length.
-The `compress' format was not designed to allow consistency checks.
-However `gunzip' is sometimes able to detect a bad `.Z' file. If you
-get an error when uncompressing a `.Z' file, do not assume that the
-`.Z' file is correct simply because the standard `uncompress' does not
-complain. This generally means that the standard `uncompress' does not
-check its input, and happily generates garbage output. The SCO
-`compress -H' format (`lzh' compression method) does not include a CRC
-but also allows some consistency checks.
-
- Files created by `zip' can be uncompressed by `gzip' only if they
-have a single member compressed with the 'deflation' method. This
-feature is only intended to help conversion of `tar.zip' files to the
-`tar.gz' format. To extract a `zip' file with a single member, use a
-command like `gunzip <foo.zip' or `gunzip -S .zip foo.zip'. To extract
-`zip' files with several members, use `unzip' instead of `gunzip'.
-
- `zcat' is identical to `gunzip -c'. `zcat' uncompresses either a
-list of files on the command line or its standard input and writes the
-uncompressed data on standard output. `zcat' will uncompress files
-that have the correct magic number whether they have a `.gz' suffix or
-not.
-
- `gzip' uses the Lempel-Ziv algorithm used in `zip' and PKZIP. The
-amount of compression obtained depends on the size of the input and the
-distribution of common substrings. Typically, text such as source code
-or English is reduced by 60-70%. Compression is generally much better
-than that achieved by LZW (as used in `compress'), Huffman coding (as
-used in `pack'), or adaptive Huffman coding (`compact').
-
- Compression is always performed, even if the compressed file is
-slightly larger than the original. The worst case expansion is a few
-bytes for the `gzip' file header, plus 5 bytes every 32K block, or an
-expansion ratio of 0.015% for large files. Note that the actual number
-of used disk blocks almost never increases. `gzip' preserves the mode,
-ownership and timestamps of files when compressing or decompressing.
-
- The `gzip' file format is specified in P. Deutsch, GZIP file format
-specification version 4.3, Internet RFC 1952
-(ftp://ftp.isi.edu/in-notes/rfc1952.txt) (May 1996). The `zip'
-deflation format is specified in P. Deutsch, DEFLATE Compressed Data
-Format Specification version 1.3, Internet RFC 1951
-(ftp://ftp.isi.edu/in-notes/rfc1951.txt) (May 1996).

- -h --help give this help
- -l --list list compressed file contents
- -L --license display software license
- -n --no-name do not save or restore the original name and time stamp
- -N --name save or restore the original name and time stamp
- -q --quiet suppress all warnings
- -r --recursive operate recursively on directories
- -S .suf --suffix .suf use suffix .suf on compressed files
- -t --test test compressed file integrity
- -v --verbose verbose mode

- -1 --fast compress faster
- -9 --best compress better
- file... files to (de)compress. If none given, use standard input.
- Report bugs to <bug-gzip@gnu.org>.
-
- This is the output of the command `gzip -v texinfo.tex':
-
- texinfo.tex: 69.7% -- replaced with texinfo.tex.gz
-
- The following command will find all `gzip' files in the current
-directory and subdirectories, and extract them in place without
-destroying the original:

-Invoking `gzip'
-***************
-
- The format for running the `gzip' program is:
-
- gzip OPTION ...
-
- `gzip' supports the following options:
-
-`--stdout'
-`--to-stdout'
-`-c'
- Write output on standard output; keep original files unchanged.
- If there are several input files, the output consists of a
- sequence of independently compressed members. To obtain better
- compression, concatenate all input files before compressing them.
-
-`--decompress'
-`--uncompress'
-`-d'
- Decompress.
-
-`--force'
-`-f'
- Force compression or decompression even if the file has multiple
- links or the corresponding file already exists, or if the
- compressed data is read from or written to a terminal. If the
- input data is not in a format recognized by `gzip', and if the
- option `--stdout' is also given, copy the input data without
- change to the standard output: let `zcat' behave as `cat'. If `-f'
- is not given, and when not running in the background, `gzip'
- prompts to verify whether an existing file should be overwritten.
-
-`--help'
-`-h'
- Print an informative help message describing the options then quit.
-
-`--list'
-`-l'
- For each compressed file, list the following fields:
-
- compressed size: size of the compressed file
- uncompressed size: size of the uncompressed file
- ratio: compression ratio (0.0% if unknown)
- uncompressed_name: name of the uncompressed file
-
- The uncompressed size is given as `-1' for files not in `gzip'
- format, such as compressed `.Z' files. To get the uncompressed
- size for such a file, you can use:
-
- zcat file.Z | wc -c
-
- In combination with the `--verbose' option, the following fields
- are also displayed:
-
- method: compression method (deflate,compress,lzh,pack)
- crc: the 32-bit CRC of the uncompressed data
- date & time: time stamp for the uncompressed file
-
- The crc is given as ffffffff for a file not in gzip format.
-
- With `--verbose', the size totals and compression ratio for all
- files is also displayed, unless some sizes are unknown. With
- `--quiet', the title and totals lines are not displayed.
-
- The `gzip' format represents the the input size modulo 2^32, so
- the uncompressed size and compression ratio are listed incorrectly
- for uncompressed files 4 GB and larger. To work around this
- problem, you can use the following command to discover a large
- uncompressed file's true size:
-
- zcat file.gz | wc -c
-
-`--license'
-`-L'
- Display the `gzip' license then quit.
-
-`--no-name'
-`-n'
- When compressing, do not save the original file name and time
- stamp by default. (The original name is always saved if the name
- had to be truncated.) When decompressing, do not restore the
- original file name if present (remove only the `gzip' suffix from
- the compressed file name) and do not restore the original time
- stamp if present (copy it from the compressed file). This option
- is the default when decompressing.
-
-`--name'
-`-N'
- When compressing, always save the original file name and time
- stamp; this is the default. When decompressing, restore the
- original file name and time stamp if present. This option is
- useful on systems which have a limit on file name length or when
- the time stamp has been lost after a file transfer.
-
-`--quiet'
-`-q'
- Suppress all warning messages.
-
-`--recursive'
-`-r'
- Travel the directory structure recursively. If any of the file
- names specified on the command line are directories, `gzip' will
- descend into the directory and compress all the files it finds
- there (or decompress them in the case of `gunzip').
-
-`--suffix SUF'
-`-S SUF'
- Use suffix `SUF' instead of `.gz'. Any suffix can be given, but
- suffixes other than `.z' and `.gz' should be avoided to avoid
- confusion when files are transferred to other systems. A null
- suffix forces gunzip to try decompression on all given files
- regardless of suffix, as in:
-
- gunzip -S "" * (*.* for MSDOS)
-
- Previous versions of gzip used the `.z' suffix. This was changed to
- avoid a conflict with `pack'.
-
-`--test'
-`-t'
- Test. Check the compressed file integrity.
-
-`--verbose'
-`-v'
- Verbose. Display the name and percentage reduction for each file
- compressed.
-
-`--version'
-`-V'
- Version. Display the version number and compilation options, then
- quit.
-
-`--fast'
-`--best'
-`-N'
- Regulate the speed of compression using the specified digit N,
- where `-1' or `--fast' indicates the fastest compression method
- (less compression) and `--best' or `-9' indicates the slowest
- compression method (optimal compression). The default compression
- level is `-6' (that is, biased towards high compression at expense
- of speed).

-Advanced usage
-**************
-
- Multiple compressed files can be concatenated. In this case,
-`gunzip' will extract all members at once. If one member is damaged,
-other members might still be recovered after removal of the damaged
-member. Better compression can be usually obtained if all members are
-decompressed and then recompressed in a single step.
-
- This is an example of concatenating `gzip' files:
-
- gzip -c file1 > foo.gz
- gzip -c file2 >> foo.gz
-
- Then
-
- gunzip -c foo
-
- is equivalent to
-
- cat file1 file2
-
- In case of damage to one member of a `.gz' file, other members can
-still be recovered (if the damaged member is removed). However, you can
-get better compression by compressing all members at once:
-
- cat file1 file2 | gzip > foo.gz
-
- compresses better than
-
- gzip -c file1 file2 > foo.gz
-
- If you want to recompress concatenated files to get better
-compression, do:
-
- zcat old.gz | gzip > new.gz
-
- If a compressed file consists of several members, the uncompressed
-size and CRC reported by the `--list' option applies to the last member
-only. If you need the uncompressed size for all members, you can use:
-
- zcat file.gz | wc -c
-
- If you wish to create a single archive file with multiple members so
-that members can later be extracted independently, use an archiver such
-as `tar' or `zip'. GNU `tar' supports the `-z' option to invoke `gzip'
-transparently. `gzip' is designed as a complement to `tar', not as a
-replacement.
-
-\1f
-File: gzip.info, Node: Environment, Next: Tapes, Prev: Advanced usage, Up: Top
-
-Environment
-***********
-
- The environment variable `GZIP' can hold a set of default options for
-`gzip'. These options are interpreted first and can be overwritten by
-explicit command line parameters. For example:
-
- for sh: GZIP="-8v --name"; export GZIP
- for csh: setenv GZIP "-8v --name"
- for MSDOS: set GZIP=-8v --name
-
- On Vax/VMS, the name of the environment variable is `GZIP_OPT', to
-avoid a conflict with the symbol set for invocation of the program.
-
-\1f
-File: gzip.info, Node: Tapes, Next: Problems, Prev: Environment, Up: Top
-
-Using `gzip' on tapes
-*********************
-
- When writing compressed data to a tape, it is generally necessary to
-pad the output with zeroes up to a block boundary. When the data is
-read and the whole block is passed to `gunzip' for decompression,
-`gunzip' detects that there is extra trailing garbage after the
-compressed data and emits a warning by default if the garbage contains
-nonzero bytes. You have to use the `--quiet' option to suppress the
-warning. This option can be set in the `GZIP' environment variable, as
-in:
-
- for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0
- for csh: (setenv GZIP "-q"; tar -xfz --block-compress /dev/rst0)
-
- In the above example, `gzip' is invoked implicitly by the `-z'
-option of GNU `tar'. Make sure that the same block size (`-b' option
-of `tar') is used for reading and writing compressed data on tapes.
-(This example assumes you are using the GNU version of `tar'.)

-Reporting Bugs
-**************
-
- If you find a bug in `gzip', please send electronic mail to
-<bug-gzip@gnu.org>. Include the version number, which you can find by
-running `gzip -V'. Also include in your message the hardware and
-operating system, the compiler used to compile `gzip', a description of
-the bug behavior, and the input to `gzip' that triggered the bug.

-GNU Free Documentation License
-==============================
-
- Version 1.1, March 2000
- Copyright (C) 2000 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA
-
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- 0. PREAMBLE
-
- The purpose of this License is to make a manual, textbook, or other
- written document "free" in the sense of freedom: to assure everyone
- the effective freedom to copy and redistribute it, with or without
- modifying it, either commercially or noncommercially. Secondarily,
- this License preserves for the author and publisher a way to get
- credit for their work, while not being considered responsible for
- modifications made by others.
-
- This License is a kind of "copyleft", which means that derivative
- works of the document must themselves be free in the same sense.
- It complements the GNU General Public License, which is a copyleft
- license designed for free software.
-
- We have designed this License in order to use it for manuals for
- free software, because free software needs free documentation: a
- free program should come with manuals providing the same freedoms
- that the software does. But this License is not limited to
- software manuals; it can be used for any textual work, regardless
- of subject matter or whether it is published as a printed book.
- We recommend this License principally for works whose purpose is
- instruction or reference.
-
- 1. APPLICABILITY AND DEFINITIONS
-
- This License applies to any manual or other work that contains a
- notice placed by the copyright holder saying it can be distributed
- under the terms of this License. The "Document", below, refers to
- any such manual or work. Any member of the public is a licensee,
- and is addressed as "you".
-
- A "Modified Version" of the Document means any work containing the
- Document or a portion of it, either copied verbatim, or with
- modifications and/or translated into another language.
-
- A "Secondary Section" is a named appendix or a front-matter
- section of the Document that deals exclusively with the
- relationship of the publishers or authors of the Document to the
- Document's overall subject (or to related matters) and contains
- nothing that could fall directly within that overall subject.
- (For example, if the Document is in part a textbook of
- mathematics, a Secondary Section may not explain any mathematics.)
- The relationship could be a matter of historical connection with
- the subject or with related matters, or of legal, commercial,
- philosophical, ethical or political position regarding them.
-
- The "Invariant Sections" are certain Secondary Sections whose
- titles are designated, as being those of Invariant Sections, in
- the notice that says that the Document is released under this
- License.
-
- The "Cover Texts" are certain short passages of text that are
- listed, as Front-Cover Texts or Back-Cover Texts, in the notice
- that says that the Document is released under this License.
-
- A "Transparent" copy of the Document means a machine-readable copy,
- represented in a format whose specification is available to the
- general public, whose contents can be viewed and edited directly
- and straightforwardly with generic text editors or (for images
- composed of pixels) generic paint programs or (for drawings) some
- widely available drawing editor, and that is suitable for input to
- text formatters or for automatic translation to a variety of
- formats suitable for input to text formatters. A copy made in an
- otherwise Transparent file format whose markup has been designed
- to thwart or discourage subsequent modification by readers is not
- Transparent. A copy that is not "Transparent" is called "Opaque".
-
- Examples of suitable formats for Transparent copies include plain
- ASCII without markup, Texinfo input format, LaTeX input format,
- SGML or XML using a publicly available DTD, and
- standard-conforming simple HTML designed for human modification.
- Opaque formats include PostScript, PDF, proprietary formats that
- can be read and edited only by proprietary word processors, SGML
- or XML for which the DTD and/or processing tools are not generally
- available, and the machine-generated HTML produced by some word
- processors for output purposes only.
-
- The "Title Page" means, for a printed book, the title page itself,
- plus such following pages as are needed to hold, legibly, the
- material this License requires to appear in the title page. For
- works in formats which do not have any title page as such, "Title
- Page" means the text near the most prominent appearance of the
- work's title, preceding the beginning of the body of the text.
-
- 2. VERBATIM COPYING
-
- You may copy and distribute the Document in any medium, either
- commercially or noncommercially, provided that this License, the
- copyright notices, and the license notice saying this License
- applies to the Document are reproduced in all copies, and that you
- add no other conditions whatsoever to those of this License. You
- may not use technical measures to obstruct or control the reading
- or further copying of the copies you make or distribute. However,
- you may accept compensation in exchange for copies. If you
- distribute a large enough number of copies you must also follow
- the conditions in section 3.
-
- You may also lend copies, under the same conditions stated above,
- and you may publicly display copies.
-
- 3. COPYING IN QUANTITY
-
- If you publish printed copies of the Document numbering more than
- 100, and the Document's license notice requires Cover Texts, you
- must enclose the copies in covers that carry, clearly and legibly,
- all these Cover Texts: Front-Cover Texts on the front cover, and
- Back-Cover Texts on the back cover. Both covers must also clearly
- and legibly identify you as the publisher of these copies. The
- front cover must present the full title with all words of the
- title equally prominent and visible. You may add other material
- on the covers in addition. Copying with changes limited to the
- covers, as long as they preserve the title of the Document and
- satisfy these conditions, can be treated as verbatim copying in
- other respects.
-
- If the required texts for either cover are too voluminous to fit
- legibly, you should put the first ones listed (as many as fit
- reasonably) on the actual cover, and continue the rest onto
- adjacent pages.
-
- If you publish or distribute Opaque copies of the Document
- numbering more than 100, you must either include a
- machine-readable Transparent copy along with each Opaque copy, or
- state in or with each Opaque copy a publicly-accessible
- computer-network location containing a complete Transparent copy
- of the Document, free of added material, which the general
- network-using public has access to download anonymously at no
- charge using public-standard network protocols. If you use the
- latter option, you must take reasonably prudent steps, when you
- begin distribution of Opaque copies in quantity, to ensure that
- this Transparent copy will remain thus accessible at the stated
- location until at least one year after the last time you
- distribute an Opaque copy (directly or through your agents or
- retailers) of that edition to the public.
-
- It is requested, but not required, that you contact the authors of
- the Document well before redistributing any large number of
- copies, to give them a chance to provide you with an updated
- version of the Document.
-
- 4. MODIFICATIONS
-
- You may copy and distribute a Modified Version of the Document
- under the conditions of sections 2 and 3 above, provided that you
- release the Modified Version under precisely this License, with
- the Modified Version filling the role of the Document, thus
- licensing distribution and modification of the Modified Version to
- whoever possesses a copy of it. In addition, you must do these
- things in the Modified Version:
-
- A. Use in the Title Page (and on the covers, if any) a title
- distinct from that of the Document, and from those of
- previous versions (which should, if there were any, be listed
- in the History section of the Document). You may use the
- same title as a previous version if the original publisher of
- that version gives permission.
-
- B. List on the Title Page, as authors, one or more persons or
- entities responsible for authorship of the modifications in
- the Modified Version, together with at least five of the
- principal authors of the Document (all of its principal
- authors, if it has less than five).
-
- C. State on the Title page the name of the publisher of the
- Modified Version, as the publisher.
-
- D. Preserve all the copyright notices of the Document.
-
- E. Add an appropriate copyright notice for your modifications
- adjacent to the other copyright notices.
-
- F. Include, immediately after the copyright notices, a license
- notice giving the public permission to use the Modified
- Version under the terms of this License, in the form shown in
- the Addendum below.
-
- G. Preserve in that license notice the full lists of Invariant
- Sections and required Cover Texts given in the Document's
- license notice.
-
- H. Include an unaltered copy of this License.
-
- I. Preserve the section entitled "History", and its title, and
- add to it an item stating at least the title, year, new
- authors, and publisher of the Modified Version as given on
- the Title Page. If there is no section entitled "History" in
- the Document, create one stating the title, year, authors,
- and publisher of the Document as given on its Title Page,
- then add an item describing the Modified Version as stated in
- the previous sentence.
-
- J. Preserve the network location, if any, given in the Document
- for public access to a Transparent copy of the Document, and
- likewise the network locations given in the Document for
- previous versions it was based on. These may be placed in
- the "History" section. You may omit a network location for a
- work that was published at least four years before the
- Document itself, or if the original publisher of the version
- it refers to gives permission.
-
- K. In any section entitled "Acknowledgments" or "Dedications",
- preserve the section's title, and preserve in the section all
- the substance and tone of each of the contributor
- acknowledgments and/or dedications given therein.
-
- L. Preserve all the Invariant Sections of the Document,
- unaltered in their text and in their titles. Section numbers
- or the equivalent are not considered part of the section
- titles.
-
- M. Delete any section entitled "Endorsements". Such a section
- may not be included in the Modified Version.
-
- N. Do not retitle any existing section as "Endorsements" or to
- conflict in title with any Invariant Section.
-
- If the Modified Version includes new front-matter sections or
- appendices that qualify as Secondary Sections and contain no
- material copied from the Document, you may at your option
- designate some or all of these sections as invariant. To do this,
- add their titles to the list of Invariant Sections in the Modified
- Version's license notice. These titles must be distinct from any
- other section titles.
-
- You may add a section entitled "Endorsements", provided it contains
- nothing but endorsements of your Modified Version by various
- parties--for example, statements of peer review or that the text
- has been approved by an organization as the authoritative
- definition of a standard.
-
- You may add a passage of up to five words as a Front-Cover Text,
- and a passage of up to 25 words as a Back-Cover Text, to the end
- of the list of Cover Texts in the Modified Version. Only one
- passage of Front-Cover Text and one of Back-Cover Text may be
- added by (or through arrangements made by) any one entity. If the
- Document already includes a cover text for the same cover,
- previously added by you or by arrangement made by the same entity
- you are acting on behalf of, you may not add another; but you may
- replace the old one, on explicit permission from the previous
- publisher that added the old one.
-
- The author(s) and publisher(s) of the Document do not by this
- License give permission to use their names for publicity for or to
- assert or imply endorsement of any Modified Version.
-
- 5. COMBINING DOCUMENTS
-
- You may combine the Document with other documents released under
- this License, under the terms defined in section 4 above for
- modified versions, provided that you include in the combination
- all of the Invariant Sections of all of the original documents,
- unmodified, and list them all as Invariant Sections of your
- combined work in its license notice.
-
- The combined work need only contain one copy of this License, and
- multiple identical Invariant Sections may be replaced with a single
- copy. If there are multiple Invariant Sections with the same name
- but different contents, make the title of each such section unique
- by adding at the end of it, in parentheses, the name of the
- original author or publisher of that section if known, or else a
- unique number. Make the same adjustment to the section titles in
- the list of Invariant Sections in the license notice of the
- combined work.
-
- In the combination, you must combine any sections entitled
- "History" in the various original documents, forming one section
- entitled "History"; likewise combine any sections entitled
- "Acknowledgments", and any sections entitled "Dedications". You
- must delete all sections entitled "Endorsements."
-
- 6. COLLECTIONS OF DOCUMENTS
-
- You may make a collection consisting of the Document and other
- documents released under this License, and replace the individual
- copies of this License in the various documents with a single copy
- that is included in the collection, provided that you follow the
- rules of this License for verbatim copying of each of the
- documents in all other respects.
-
- You may extract a single document from such a collection, and
- distribute it individually under this License, provided you insert
- a copy of this License into the extracted document, and follow
- this License in all other respects regarding verbatim copying of
- that document.
-
- 7. AGGREGATION WITH INDEPENDENT WORKS
-
- A compilation of the Document or its derivatives with other
- separate and independent documents or works, in or on a volume of
- a storage or distribution medium, does not as a whole count as a
- Modified Version of the Document, provided no compilation
- copyright is claimed for the compilation. Such a compilation is
- called an "aggregate", and this License does not apply to the
- other self-contained works thus compiled with the Document, on
- account of their being thus compiled, if they are not themselves
- derivative works of the Document.
-
- If the Cover Text requirement of section 3 is applicable to these
- copies of the Document, then if the Document is less than one
- quarter of the entire aggregate, the Document's Cover Texts may be
- placed on covers that surround only the Document within the
- aggregate. Otherwise they must appear on covers around the whole
- aggregate.
-
- 8. TRANSLATION
-
- Translation is considered a kind of modification, so you may
- distribute translations of the Document under the terms of section
- 4. Replacing Invariant Sections with translations requires special
- permission from their copyright holders, but you may include
- translations of some or all Invariant Sections in addition to the
- original versions of these Invariant Sections. You may include a
- translation of this License provided that you also include the
- original English version of this License. In case of a
- disagreement between the translation and the original English
- version of this License, the original English version will prevail.
-
- 9. TERMINATION
-
- You may not copy, modify, sublicense, or distribute the Document
- except as expressly provided for under this License. Any other
- attempt to copy, modify, sublicense or distribute the Document is
- void, and will automatically terminate your rights under this
- License. However, parties who have received copies, or rights,
- from you under this License will not have their licenses
- terminated so long as such parties remain in full compliance.
-
- 10. FUTURE REVISIONS OF THIS LICENSE
-
- The Free Software Foundation may publish new, revised versions of
- the GNU Free Documentation License from time to time. Such new
- versions will be similar in spirit to the present version, but may
- differ in detail to address new problems or concerns. See
- `http://www.gnu.org/copyleft/'.
-
- Each version of the License is given a distinguishing version
- number. If the Document specifies that a particular numbered
- version of this License "or any later version" applies to it, you
- have the option of following the terms and conditions either of
- that specified version or of any later version that has been
- published (not as a draft) by the Free Software Foundation. If
- the Document does not specify a version number of this License,
- you may choose any version ever published (not as a draft) by the
- Free Software Foundation.
-
-ADDENDUM: How to use this License for your documents
-----------------------------------------------------
-
- To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and license
-notices just after the title page:
-
- Copyright (C) YEAR YOUR NAME.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.1
- or any later version published by the Free Software Foundation;
- with the Invariant Sections being LIST THEIR TITLES, with the
- Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
- A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-
- If you have no Invariant Sections, write "with no Invariant Sections"
-instead of saying which ones are invariant. If you have no Front-Cover
-Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being
-LIST"; likewise for Back-Cover Texts.
-
- If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License, to
-permit their use in free software.

-@code{gzip} reduces the size of the named files using Lempel-Ziv coding
-(LZ77). Whenever possible, each file is replaced by one with the
-extension @samp{.gz}, while keeping the same ownership modes, access and
-modification times. (The default extension is @samp{-gz} for VMS,
-@samp{z} for MSDOS, OS/2 FAT and Atari.) If no files are specified or
-if a file name is "-", the standard input is compressed to the standard
-output. @code{gzip} will only attempt to compress regular files. In
-particular, it will ignore symbolic links.
-
-If the new file name is too long for its file system, @code{gzip}
-truncates it. @code{gzip} attempts to truncate only the parts of the
-file name longer than 3 characters. (A part is delimited by dots.) If
-the name consists of small parts only, the longest parts are truncated.
-For example, if file names are limited to 14 characters, gzip.msdos.exe
-is compressed to gzi.msd.exe.gz. Names are not truncated on systems
-which do not have a limit on file name length.
-
-By default, @code{gzip} keeps the original file name and timestamp in
-the compressed file. These are used when decompressing the file with the
-@samp{-N} option. This is useful when the compressed file name was
-truncated or when the time stamp was not preserved after a file
-transfer.
-
-Compressed files can be restored to their original form using @samp{gzip -d}
-or @code{gunzip} or @code{zcat}. If the original name saved in the
-compressed file is not suitable for its file system, a new name is
-constructed from the original one to make it legal.
-
-@code{gunzip} takes a list of files on its command line and replaces
-each file whose name ends with @samp{.gz}, @samp{.z}, @samp{.Z},
-@samp{-gz}, @samp{-z} or @samp{_z} and which begins with the correct
-magic number with an uncompressed file without the original extension.
-@code{gunzip} also recognizes the special extensions @samp{.tgz} and
-@samp{.taz} as shorthands for @samp{.tar.gz} and @samp{.tar.Z}
-respectively. When compressing, @code{gzip} uses the @samp{.tgz}
-extension if necessary instead of truncating a file with a @samp{.tar}
-extension.
-
-@code{gunzip} can currently decompress files created by @code{gzip},
-@code{zip}, @code{compress} or @code{pack}. The detection of the input
-format is automatic. When using the first two formats, @code{gunzip}
-checks a 32 bit CRC (cyclic redundancy check). For @code{pack},
-@code{gunzip} checks the uncompressed length. The @code{compress} format
-was not designed to allow consistency checks. However @code{gunzip} is
-sometimes able to detect a bad @samp{.Z} file. If you get an error when
-uncompressing a @samp{.Z} file, do not assume that the @samp{.Z} file is
-correct simply because the standard @code{uncompress} does not complain.
-This generally means that the standard @code{uncompress} does not check
-its input, and happily generates garbage output. The SCO @samp{compress
--H} format (@code{lzh} compression method) does not include a CRC but
-also allows some consistency checks.
-
-Files created by @code{zip} can be uncompressed by @code{gzip} only if
-they have a single member compressed with the 'deflation' method. This
-feature is only intended to help conversion of @code{tar.zip} files to
-the @code{tar.gz} format. To extract a @code{zip} file with a single
-member, use a command like @samp{gunzip <foo.zip} or @samp{gunzip -S
-.zip foo.zip}. To extract @code{zip} files with several
-members, use @code{unzip} instead of @code{gunzip}.
-
-@code{zcat} is identical to @samp{gunzip -c}. @code{zcat}
-uncompresses either a list of files on the command line or its standard
-input and writes the uncompressed data on standard output. @code{zcat}
-will uncompress files that have the correct magic number whether they
-have a @samp{.gz} suffix or not.
-
-@code{gzip} uses the Lempel-Ziv algorithm used in @code{zip} and PKZIP.
-The amount of compression obtained depends on the size of the input and
-the distribution of common substrings. Typically, text such as source
-code or English is reduced by 60-70%. Compression is generally much
-better than that achieved by LZW (as used in @code{compress}), Huffman
-coding (as used in @code{pack}), or adaptive Huffman coding
-(@code{compact}).
-
-Compression is always performed, even if the compressed file is slightly
-larger than the original. The worst case expansion is a few bytes for
-the @code{gzip} file header, plus 5 bytes every 32K block, or an expansion
-ratio of 0.015% for large files. Note that the actual number of used
-disk blocks almost never increases. @code{gzip} preserves the mode,
-ownership and timestamps of files when compressing or decompressing.
-
-The @code{gzip} file format is specified in P. Deutsch, @sc{gzip} file
-format specification version 4.3,
-@uref{ftp://ftp.isi.edu/in-notes/rfc1952.txt, Internet RFC 1952} (May
-1996). The @code{zip} deflation format is specified in P. Deutsch,
-@sc{deflate} Compressed Data Format Specification version 1.3,
-@uref{ftp://ftp.isi.edu/in-notes/rfc1951.txt, Internet RFC 1951} (May

-
-The following command will find all @code{gzip} files in the current

-@chapter Invoking @code{gzip}
-@cindex invoking
-@cindex options
-
-The format for running the @code{gzip} program is:
-
-@example
-gzip @var{option} @dots{}
-@end example
-
-@code{gzip} supports the following options:
-
-@table @samp
-@item --stdout
-@itemx --to-stdout
-@itemx -c
-Write output on standard output; keep original files unchanged.
-If there are several input files, the output consists of a sequence of
-independently compressed members. To obtain better compression,
-concatenate all input files before compressing them.
-
-@item --decompress
-@itemx --uncompress
-@itemx -d
-Decompress.
-
-@item --force
-@itemx -f
-Force compression or decompression even if the file has multiple links
-or the corresponding file already exists, or if the compressed data
-is read from or written to a terminal. If the input data is not in
-a format recognized by @code{gzip}, and if the option @samp{--stdout} is also
-given, copy the input data without change to the standard output: let
-@code{zcat} behave as @code{cat}. If @samp{-f} is not given, and
-when not running in the background, @code{gzip} prompts to verify
-whether an existing file should be overwritten.
-
-@item --help
-@itemx -h
-Print an informative help message describing the options then quit.
-
-@item --list
-@itemx -l
-For each compressed file, list the following fields:
-
-@example
-compressed size: size of the compressed file
-uncompressed size: size of the uncompressed file
-ratio: compression ratio (0.0% if unknown)
-uncompressed_name: name of the uncompressed file
-@end example
-
-The uncompressed size is given as @samp{-1} for files not in @code{gzip}
-format, such as compressed @samp{.Z} files. To get the uncompressed size for
-such a file, you can use:
-
-@example
-zcat file.Z | wc -c
-@end example
-
-In combination with the @samp{--verbose} option, the following fields are also
-displayed:
-
-@example
-method: compression method (deflate,compress,lzh,pack)
-crc: the 32-bit CRC of the uncompressed data
-date & time: time stamp for the uncompressed file
-@end example
-
-The crc is given as ffffffff for a file not in gzip format.
-
-With @samp{--verbose}, the size totals and compression ratio for all files
-is also displayed, unless some sizes are unknown. With @samp{--quiet},
-the title and totals lines are not displayed.
-
-The @code{gzip} format represents the the input size modulo
-@math{2^32}, so the uncompressed size and compression ratio are listed
-incorrectly for uncompressed files 4 GB and larger. To work around
-this problem, you can use the following command to discover a large
-uncompressed file's true size:
-
-@example
-zcat file.gz | wc -c
-@end example
-
-@item --license
-@itemx -L
-Display the @code{gzip} license then quit.
-
-@item --no-name
-@itemx -n
-When compressing, do not save the original file name and time stamp by
-default. (The original name is always saved if the name had to be
-truncated.) When decompressing, do not restore the original file name
-if present (remove only the @code{gzip}
-suffix from the compressed file name) and do not restore the original
-time stamp if present (copy it from the compressed file). This option
-is the default when decompressing.
-
-@item --name
-@itemx -N
-When compressing, always save the original file name and time stamp; this
-is the default. When decompressing, restore the original file name and
-time stamp if present. This option is useful on systems which have
-a limit on file name length or when the time stamp has been lost after
-a file transfer.
-
-@item --quiet
-@itemx -q
-Suppress all warning messages.
-
-@item --recursive
-@itemx -r
-Travel the directory structure recursively. If any of the file names
-specified on the command line are directories, @code{gzip} will descend
-into the directory and compress all the files it finds there (or
-decompress them in the case of @code{gunzip}).
-
-@item --suffix @var{suf}
-@itemx -S @var{suf}
-Use suffix @samp{@var{suf}} instead of @samp{.gz}. Any suffix can be
-given, but suffixes other than @samp{.z} and @samp{.gz} should be
-avoided to avoid confusion when files are transferred to other systems.
-A null suffix forces gunzip to try decompression on all given files
-regardless of suffix, as in:
-
-@example
-gunzip -S "" * (*.* for MSDOS)
-@end example
-
-Previous versions of gzip used the @samp{.z} suffix. This was changed to
-avoid a conflict with @code{pack}.
-
-@item --test
-@itemx -t
-Test. Check the compressed file integrity.
-
-@item --verbose
-@itemx -v
-Verbose. Display the name and percentage reduction for each file compressed.
-
-@item --version
-@itemx -V
-Version. Display the version number and compilation options, then quit.
-
-@item --fast
-@itemx --best
-@itemx -@var{n}
-Regulate the speed of compression using the specified digit @var{n},
-where @samp{-1} or @samp{--fast} indicates the fastest compression
-method (less compression) and @samp{--best} or @samp{-9} indicates the
-slowest compression method (optimal compression). The default
-compression level is @samp{-6} (that is, biased towards high compression at
-expense of speed).
-@end table
-
-@node Advanced usage, Environment, Invoking gzip, Top
-@chapter Advanced usage
-@cindex concatenated files
-
-Multiple compressed files can be concatenated. In this case,
-@code{gunzip} will extract all members at once. If one member is
-damaged, other members might still be recovered after removal of the
-damaged member. Better compression can be usually obtained if all
-members are decompressed and then recompressed in a single step.
-
-This is an example of concatenating @code{gzip} files:
-
-@example
-gzip -c file1 > foo.gz
-gzip -c file2 >> foo.gz
-@end example
-
-Then
-
-@example
-gunzip -c foo
-@end example
-
-is equivalent to
-
-@example
-cat file1 file2
-@end example
-
-In case of damage to one member of a @samp{.gz} file, other members can
-still be recovered (if the damaged member is removed). However,
-you can get better compression by compressing all members at once:
-
-@example
-cat file1 file2 | gzip > foo.gz
-@end example
-
-compresses better than
-
-@example
-gzip -c file1 file2 > foo.gz
-@end example
-
-If you want to recompress concatenated files to get better compression, do:
-
-@example
-zcat old.gz | gzip > new.gz
-@end example
-
-If a compressed file consists of several members, the uncompressed
-size and CRC reported by the @samp{--list} option applies to the last member
-only. If you need the uncompressed size for all members, you can use:
-
-@example
-zcat file.gz | wc -c
-@end example
-
-If you wish to create a single archive file with multiple members so
-that members can later be extracted independently, use an archiver such
-as @code{tar} or @code{zip}. GNU @code{tar} supports the @samp{-z}
-option to invoke @code{gzip} transparently. @code{gzip} is designed as a
-complement to @code{tar}, not as a replacement.
-
-@node Environment, Tapes, Advanced usage, Top
-@chapter Environment
-@cindex Environment
-
-The environment variable @code{GZIP} can hold a set of default options for
-@code{gzip}. These options are interpreted first and can be overwritten by
-explicit command line parameters. For example:
-
-@example
-for sh: GZIP="-8v --name"; export GZIP
-for csh: setenv GZIP "-8v --name"
-for MSDOS: set GZIP=-8v --name
-@end example
-
-On Vax/VMS, the name of the environment variable is @code{GZIP_OPT}, to
-avoid a conflict with the symbol set for invocation of the program.
-
-@node Tapes, Problems, Environment, Top
-@chapter Using @code{gzip} on tapes
-@cindex tapes
-
-When writing compressed data to a tape, it is generally necessary to pad
-the output with zeroes up to a block boundary. When the data is read and
-the whole block is passed to @code{gunzip} for decompression,
-@code{gunzip} detects that there is extra trailing garbage after the
-compressed data and emits a warning by default if the garbage contains
-nonzero bytes. You have to use the
-@samp{--quiet} option to suppress the warning. This option can be set in the
-@code{GZIP} environment variable, as in:
-
-@example
-for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0
-for csh: (setenv GZIP "-q"; tar -xfz --block-compress /dev/rst0)
-@end example
-
-In the above example, @code{gzip} is invoked implicitly by the @samp{-z}
-option of GNU @code{tar}. Make sure that the same block size (@samp{-b}
-option of @code{tar}) is used for reading and writing compressed data on
-tapes. (This example assumes you are using the GNU version of
-@code{tar}.)

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-%
-% For those who want to use more than one line's worth of words in
-% the preamble, break the line within one argument and it
-% will parse correctly, i.e.,
-%
-% @multitable {Column 1 template} {Column 2 template} {Column 3
-% template}
-% Not:
-% @multitable {Column 1 template} {Column 2 template}
-% {Column 3 template}
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab, @multitable or @end multitable do not need to be on their
-% own lines, but it will not hurt if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.
-% 0pt means it depends on current normal line spacing.
