       tar - The GNU version of	the tar	archiving utility

       tar [OPTION...] [FILE]...

       GNU `tar' saves many files together into	a single tape or disk archive,
       and can restore individual files	from the archive.

       tar -cf archive.tar foo bar
	      #	Create archive.tar from	files foo and bar.

       tar -tvf	archive.tar
	      #	List all files in archive.tar verbosely.

       tar -xf archive.tar
	      #	Extract	all files from archive.tar.

	      Main operation mode:

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

       -c, --create
	      create a new archive

       -d, --diff, --compare
	      find differences between archive and file	system

	      delete from the archive (not on mag tapes!)

       -r, --append
	      append files to the end of an archive

       -t, --list
	      list the contents	of an archive

	      test the archive volume label and	exit

       -u, --update
	      only append files	newer than copy	in archive

       -x, --extract, --get
	      extract files from an archive

	      Operation	modifiers:

	      check  device  numbers  when   creating	incremental   archives

       -g, --listed-incremental=FILE
	      handle new GNU-format incremental	backup

       -G, --incremental
	      handle old GNU-format incremental	backup

	      do not exit with nonzero on unreadable files

	      dump level for created listed-incremental	archive

       -n, --seek
	      archive is seekable

	      do not check device numbers when creating	incremental archives

	      archive is not seekable

	      process  only  the  NUMBERth  occurrence of each file in the ar-
	      chive; this option is valid only in conjunction with one of  the
	      subcommands  --delete,  --diff,  --extract  or --list and	when a
	      list of files is given either on the command line	or via the  -T
	      option; NUMBER defaults to 1

	      set version of the sparse	format to use (implies --sparse)

       -S, --sparse
	      handle sparse files efficiently

	      Overwrite	control:

       -k, --keep-old-files
	      don't replace existing files when	extracting

	      don't  replace  existing files that are newer than their archive

	      preserve metadata	of existing directories

	      overwrite	existing files when extracting

	      overwrite	 metadata  of  existing	 directories  when  extracting

	      empty hierarchies	prior to extracting directory

	      remove files after adding	them to	the archive

       -U, --unlink-first
	      remove each file prior to	extracting over	it

       -W, --verify
	      attempt to verify	the archive after writing it

	      Select output stream:

       --ignore-command-error ignore exit codes	of children

	      treat non-zero exit codes	of children as error

       -O, --to-stdout
	      extract files to standard	output

	      pipe extracted files to another program

	      Handling of file attributes:

	      preserve	access	times on dumped	files, either by restoring the
	      times after reading (METHOD='replace'; default) or by  not  set-
	      ting the times in	the first place	(METHOD='system')

	      delay  setting  modification  times and permissions of extracted
	      directories until	the end	of extraction

	      force NAME as group for added files

	      force (symbolic) mode CHANGES for	added files

	      set mtime	for added files	from DATE-OR-FILE

       -m, --touch
	      don't extract file modified time

	      cancel the effect	of --delay-directory-restore option

	      extract files as yourself	(default for ordinary users)

	      apply the	user's umask when extracting permissions from the  ar-
	      chive (default for ordinary users)

	      always use numbers for user/group	names

	      force NAME as owner for added files

       -p, --preserve-permissions, --same-permissions
	      extract  information  about  file	permissions (default for supe-

	      same as both -p and -s

	      try extracting files with	the same ownership as  exists  in  the
	      archive (default for superuser)

       -s, --preserve-order, --same-order
	      sort names to extract to match archive

	      Device selection and switching:

       -f, --file=ARCHIVE
	      use archive file or device ARCHIVE

	      archive file is local even if it has a colon

       -F, --info-script=NAME, --new-volume-script=NAME
	      run script at end	of each	tape (implies -M)

       -L, --tape-length=NUMBER
	      change tape after	writing	NUMBER x 1024 bytes

       -M, --multi-volume
	      create/list/extract multi-volume archive

	      use given	rmt COMMAND instead of rmt

	      use remote COMMAND instead of rsh

	      use/update the volume number in FILE

	      Device blocking:

       -b, --blocking-factor=BLOCKS
	      BLOCKS x 512 bytes per record

       -B, --read-full-records
	      reblock as we read (for 4.2BSD pipes)

       -i, --ignore-zeros
	      ignore zeroed blocks in archive (means EOF)

	      NUMBER of	bytes per record, multiple of 512

	      Archive format selection:

       -H, --format=FORMAT
	      create archive of	the given format

	      FORMAT is	one of the following:

       gnu    GNU tar 1.13.x format

       oldgnu GNU format as per	tar <= 1.12

       pax    POSIX 1003.1-2001	(pax) format
