-.It Fl t
-Reset the access times of any file or directory read or accessed by
-.Nm pax
-to be the same as they were before being read or accessed by
-.Nm pax .
-.It Fl u
-Ignore files that are older (having a less recent file modification time)
-than a pre-existing file or archive member with the same name.
-During
-.Em read ,
-an archive member with the same name as a file in the file system will be
-extracted if the archive member is newer than the file.
-During
-.Em write ,
-a file system member with the same name as an archive member will be
-written to the archive if it is newer than the archive member.
-During
-.Em copy ,
-the file in the destination hierarchy is replaced by the file in the source
-hierarchy or by a link to the file in the source hierarchy if the file in
-the source hierarchy is newer.
-.It Fl v
-During a
-.Em list
-operation, produce a verbose table of contents using the format of the
-.Xr ls 1
-utility with the
-.Fl l
-option.
-For pathnames representing a hard link to a previous member of the archive,
-the output has the format:
-.Dl <ls -l listing> == <link name>
-For pathnames representing a symbolic link, the output has the format:
-.Dl <ls -l listing> => <link name>
-Where <ls -l listing> is the output format specified by the
-.Xr ls 1
-utility when used with the
-.Fl l
-option.
-Otherwise for all the other operational modes
-.Po Em read , write , Li and Em copy
-.Pc ,
-pathnames are written and flushed to
-.Dv standard error
-without a trailing
-.Dv <newline>
-as soon as processing begins on that file or
-archive member.
-The trailing
-.Dv <newline> ,
-is not buffered, and is written only after the file has been read or written.
-.It Fl x Ar format
-Specify the output archive format, with the default format being
-.Ar ustar .
-.Nm pax
-currently supports the following formats:
-.Bl -tag -width "sv4cpio"
-.It Ar cpio
-The extended cpio interchange format specified in the
-.St -p1003.2
-standard.
-The default blocksize for this format is 5120 bytes.
-Inode and device information about a file (used for detecting file hard links
-by this format) which may be truncated by this format is detected by
-.Nm pax
-and is repaired.
-.It Ar bcpio
-The old binary cpio format.
-The default blocksize for this format is 5120 bytes.
-This format is not very portable and should not be used when other formats
-are available.
-Inode and device information about a file (used for detecting file hard links
-by this format) which may be truncated by this format is detected by
-.Nm pax
-and is repaired.
-.It Ar sv4cpio
-The System V release 4 cpio.
-The default blocksize for this format is 5120 bytes.
-Inode and device information about a file (used for detecting file hard links
-by this format) which may be truncated by this format is detected by
-.Nm pax
-and is repaired.
-.It Ar sv4crc
-The System V release 4 cpio with file crc checksums.
-The default blocksize for this format is 5120 bytes.
-Inode and device information about a file (used for detecting file hard links
-by this format) which may be truncated by this format is detected by
-.Nm pax
-and is repaired.
-.It Ar tar
-The old BSD tar format as found in BSD4.3.
-The default blocksize for this format is 10240 bytes.
-Pathnames stored by this format must be 100 characters or less in length.
-Only
-.Em regular
-files,
-.Em hard links , soft links ,
-and
-.Em directories
-will be archived (other file system types are not supported).
-For backwards compatibility with even older tar formats, a
-.Fl o
-option can be used when writing an archive to omit the storage of directories.
-This option takes the form:
-.Dl Fl o Cm write_opt=nodir
-.It Ar ustar
-The extended tar interchange format specified in the
-.St -p1003.2
-standard.
-The default blocksize for this format is 10240 bytes.
-Pathnames stored by this format must be 250 characters or less in length.
-.El
-.Pp
-.Nm pax
-will detect and report any file that it is unable to store or extract
-as the result of any specific archive format restrictions.
-The individual archive formats may impose additional restrictions on use.
-Typical archive format restrictions include (but are not limited to):
-file pathname length, file size, link pathname length, and the type of the
-file.
-.It Fl B Ar bytes
-Limit the number of bytes written to a single archive volume to
-.Ar bytes .
-The
-.Ar bytes
-limit can end with
-.Sq Li m ,
-.Sq Li k ,
-or
-.Sq Li b
-to specify multiplication by 1048576 (1M), 1024 (1K) or 512, respectively.
-A pair of
-.Ar bytes
-limits can be separated by
-.Sq Li x
-to indicate a product.
-.Pp
-.Em Warning :
-Only use this option when writing an archive to a device which supports
-an end of file read condition based on last (or largest) write offset
-(such as a regular file or a tape drive).
-The use of this option with a floppy or hard disk is not recommended.
-.It Fl D
-This option is the same as the
-.Fl u
-option, except that the file inode change time is checked instead of the
-file modification time.
-The file inode change time can be used to select files whose inode information
-(e.g. UID, GID, etc.) is newer than a copy of the file in the destination
-.Ar directory .
-.It Fl E Ar limit
-Limit the number of consecutive read faults while trying to read a flawed
-archive to
-.Ar limit .
-With a positive
-.Ar limit ,
-.Nm pax
-will attempt to recover from an archive read error and will
-continue processing starting with the next file stored in the archive.
-A
-.Ar limit
-of 0 will cause
-.Nm pax
-to stop operation after the first read error is detected on an archive volume.
-A
-.Ar limit
-of
-.Li NONE
-will cause
-.Nm pax
-to attempt to recover from read errors forever.
-The default
-.Ar limit
-is a small positive number of retries.
-.Pp
-.Em Warning:
-Using this option with
-.Li NONE
-should be used with extreme caution as
-.Nm pax
-may get stuck in an infinite loop on a very badly flawed archive.
-.It Fl G Ar group
-Select a file based on its
-.Ar group
-name, or when starting with a
-.Cm # ,
-a numeric gid.
-A '\\' can be used to escape the
-.Cm # .
-Multiple
-.Fl G
-options may be supplied and checking stops with the first match.
-.It Fl H
-Follow only command line symbolic links while performing a physical file
-system traversal.
-.It Fl L
-Follow all symbolic links to perform a logical file system traversal.
-.It Fl P
-Do not follow symbolic links, perform a physical file system traversal.
-This is the default mode.
-.It Fl T Ar [from_date][,to_date][/[c][m]]
