Linux 2.6 - man page for tar (linux section 1)

TAR(1)				   BSD General Commands Manual				   TAR(1)

     tar -- The GNU version of the tar archiving utility

     tar [-] A --catenate --concatenate | c --create | d --diff --compare | --delete | r --append
	 | t --list | --test-label | u --update | x --extract --get [options] [pathname ...]

     Tar stores and extracts files from a tape or disk archive.

     The first argument to tar should be a function; either one of the letters Acdrtux, or one of
     the long function names.  A function letter need not be prefixed with ``-'', and may be com-
     bined with other single-letter options.  A long function name must be prefixed with --.
     Some options take a parameter; with the single-letter form these must be given as separate
     arguments.  With the long form, they may be given by appending =value to the option.

     Main operation mode:

     -A, --catenate, --concatenate
	   append tar files to an archive

     -c, --create

     The behavior of tar is controlled by the following environment variables, among others:

	     Backup prefix to use when extracting, if --suffix is not specified.  The backup suf-
	     fix defaults to `~' if neither is specified.

	     Options to prepend to those specified on the command line, separated by whitespace.
	     Embedded backslashes may be used to escape whitespace or backslashes within an

     TAPE    Device or file to use for the archive if --file is not specified.	If this environ-
	     ment variable is unset, use stdin or stdout instead.


     Create archive.tar from files foo and bar.
	   tar -cf archive.tar foo bar
     List all files in archive.tar verbosely.
	   tar -tvf archive.tar
     Extract all files from archive.tar.
	   tar -xf archive.tar

     tar(5), symlink(7), rmt(8)

     The tar command appeared in Version 7 AT&T UNIX.

     The GNU folks, in general, abhor man pages, and create info documents instead.  Unfortu-
     nately, the info document describing tar is licensed under the GFDL with invariant cover
     texts, which makes it impossible to include any text from that document in this man page.
     Most of the text in this document was automatically extracted from the usage text in the
     source.  It may not completely describe all features of the program.
