+
+1mDESCRIPTION0m
+       4mGzip24m  reduces  the	size  of  the  named  files using Lempel-Ziv coding
+       (LZ77).	Whenever possible, each file  is  replaced  by	one  with  the
+       extension 1m.gz22m, while keeping the same ownership modes, access and modi-
+       fication times.	(The default extension is 1m-gz 22mfor VMS,  1mz  22mfor  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
+       output.	4mGzip24m will only attempt to compress regular files.	In particu-
+       lar, it will ignore symbolic links.
+
+       If the compressed file name is too long for its file system, 4mgzip24m trun-
+       cates  it.   4mGzip24m  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, 4mgzip24m keeps the original file name and timestamp in the com-
+       pressed	file.  These  are used when decompressing the file with the 1m-N0m
+       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 4mgzip24m 4m-d0m
+       or 4mgunzip24m or 4mzcat24m.  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.
+
+       4mgunzip24m takes a list of files on its command line and replaces each file
+       whose  name ends with .gz, -gz, .z, -z, or _z (ignoring case) and which
+       begins with the correct magic number with an uncompressed file  without
+       the  original extension.	 4mgunzip24m also recognizes the special extensions
+       1m.tgz 22mand 1m.taz 22mas shorthands for 1m.tar.gz 22mand 1m.tar.Z 22mrespectively.   When
+       compressing, 4mgzip24m uses the 1m.tgz 22mextension if necessary instead of trun-
+       cating a file with a 1m.tar 22mextension.
+
+       4mgunzip24m can currently decompress files created by 4mgzip24m,	 4mzip24m,  4mcompress24m,
+       4mcompress24m  4m-H24m  or 4mpack24m.  The detection of the input format is automatic.
+       When using the first two formats, 4mgunzip24m checks a 32 bit CRC. For  4mpack0m
+       and 4mgunzip24m checks the uncompressed length. The standard 4mcompress24m format
+       was not designed to allow consistency checks. However 4mgunzip24m  is  some-
+       times  able  to	detect	a bad .Z file. If you get an error when uncom-
+       pressing a .Z file, do not assume that the .Z file  is  correct	simply
+       because the standard 4muncompress24m does not complain. This generally means
+       that the standard 4muncompress24m does not check its input, and happily gen-
+       erates  garbage	output.	  The  SCO compress -H format (lzh compression
+       method) does not include a CRC but also allows some consistency checks.
+
+       Files created by 4mzip24m 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 4mzip24m file with a single member, use a command like 4mgunzip0m
+       4m<foo.zip24m or 4mgunzip24m 4m-S24m 4m.zip24m 4mfoo.zip24m.  To extract zip files with	several
+       members, use 4munzip24m instead of 4mgunzip24m.
+
+       4mzcat24m  is  identical	 to  4mgunzip24m  1m-c22m.   (On  some	systems,  4mzcat24m may be
+       installed as 4mgzcat24m to preserve the original link  to  4mcompress24m.)   4mzcat0m
+       uncompresses either a list of files on the command line or its standard
+       input and writes the uncompressed data on standard output.   4mzcat24m  will
+       uncompress files that have the correct magic number whether they have a
+       1m.gz 22msuffix or not.
+
+       4mGzip24m uses the Lempel-Ziv algorithm used in 4mzip24m and PKZIP.   The  amount
+       of  compression	obtained depends on the size of the input and the dis-
+       tribution 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  4mcompress24m),  Huffman	coding	(as
+       used in 4mpack24m), or adaptive Huffman coding (4mcompact24m).
+
+       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.  4mgzip24m preserves the mode,
+       ownership and timestamps of files when compressing or decompressing.
+
+1mOPTIONS0m
+       1m-a --ascii0m
+	      Ascii text mode: convert end-of-lines using  local  conventions.
+	      This  option  is	supported  only	 on some non-Unix systems. For
+	      MSDOS, CR LF is converted to LF when compressing, and LF is con-
+	      verted to CR LF when decompressing.
+
+       1m-c --stdout --to-stdout0m
+	      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.
+
+       1m-d --decompress --uncompress0m
+	      Decompress.
+
+       1m-f --force0m
+	      Force compression or decompression even if the file has multiple
+	      links or the corresponding file already exists, or if  the  com-
+	      pressed data is read from or written to a terminal. If the input
+	      data is not in a format recognized by 4mgzip24m, and  if	the  option
+	      --stdout	is  also  given, copy the input data without change to
+	      the standard output: let 4mzcat24m behave	 as  4mcat24m.	 If  1m-f  22mis  not
+	      given,  and  when not running in the background, 4mgzip24m prompts to
+	      verify whether an existing file should be overwritten.
+
+       1m-h --help0m
+	      Display a help screen and quit.
+
+       1m-k --keep0m
+	      Keep (don't delete) input files during compression or decompres-
+	      sion.
+
+       1m-l --list0m
+	      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 for-
+	      mat, 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
+		  date & time: time stamp for the uncompressed file
+
+	      The compression methods currently supported  are	deflate,  com-
+	      press,  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.
+
+       1m-L --license0m
+	      Display the 4mgzip24m license and quit.
+
+       1m-n --no-name0m
+	      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 4mgzip24m 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.
+
+       1m-N --name0m
+	      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.
+
+       1m-q --quiet0m
+	      Suppress all warnings.
+
+       1m-r --recursive0m
+	      Travel  the  directory structure recursively. If any of the file
+	      names specified on the command line are directories,  4mgzip24m  will
+	      descend  into  the directory and compress all the files it finds
+	      there (or decompress them in the case of 4mgunzip24m ).
+
+       1m-S .suf --suffix .suf0m
+	      When compressing, use suffix .suf instead of .gz.	 Any non-empty
+	      suffix  can  be given, but suffixes other than .z and .gz should
+	      be avoided to avoid confusion  when  files  are  transferred  to
+	      other systems.

-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,

-
-     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	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.

-     -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:
+       1m-# --fast --best0m
+	      Regulate	the  speed of compression using the specified digit 4m#24m,
+	      where 1m-1 22mor 1m--fast	 22mindicates  the  fastest  compression  method
+	      (less  compression)  and 1m-9 22mor 1m--best 22mindicates the slowest com-
+	      pression method (best  compression).   The  default  compression

+       In  case of damage to one member of a .gz file, other members can still

+       better compression by compressing all members at once:
 
-     -#	--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).
+	     cat file1 file2 | gzip > foo.gz
 
-ADVANCED USAGE
-     Multiple compressed files can be concatenated. In this case,
-     gunzip will extract all members at	once. For example:
+       compresses better than
 
-	   gzip	-c file1  > foo.gz
-	   gzip	-c file2 >> foo.gz
+	     gzip -c file1 file2 > foo.gz
 
-     Then
+       If you want to recompress concatenated files to get better compression,
+       do:
+
+	     gzip -cd 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:
+
+	     gzip -cd file.gz | wc -c
 
-	   gunzip -c foo
+       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  transpar-
+       ently. gzip is designed as a complement to tar, not as a replacement.
+
+1mENVIRONMENT0m
+       The  environment	 variable  1mGZIP  22mcan hold a set of default options for
+       4mgzip24m.  These options are interpreted first and can	be  overwritten	 by
+       explicit command line parameters. For example:

+	     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

-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

-	   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-
