DESCRIPTION
       This manual page documents the GNU version  of  tar  ,  an
       archiving program designed to store and extract files from
       an archive file known as a tarfile.  A tarfile may be made
       on  a  tape  drive,  however, it is also common to write a
       tarfile to a normal file.  The first argument to tar  must
       be  one  of the options: Acdrtux, followed by any optional
       functions.  The final arguments to tar are  the  names  of
       the files or directories which should be archived. The use
       of a directory name always implies that the subdirectories
       below should be included in the archive.

EXAMPLES
       tar -xvvf foo.tar
              extract foo.tar

       tar -xvvzf foo.tar.gz
              extract gzipped foo.tar.gz

       tar -cvvf foo.tar foo/
              tar contents of folder foo in foo.tar

FUNCTION LETTERS
       One of the following options must be used:

       -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
              delete from the archive (not for use on mag tapes!)

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

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

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

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

OTHER OPTIONS
       --atime-preserve
              don't change access times on dumped files

       -b, --block-size N
              block size of Nx512 bytes (default N=20)

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

       -C, --directory DIR
              change to directory DIR

       --checkpoint
              print directory names while reading the archive

       -f, --file [HOSTNAME:]F
              use  archive file or device F (default "-", meaning
              stdin/stdout)

       --force-local
              archive file is local even if has a colon

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

       -G, --incremental
              create/list/extract  old   GNU-format   incremental
              backup

       -g, --listed-incremental F
              create/list/extract   new   GNU-format  incremental
              backup

       -h, --dereference
              don't dump symlinks; dump the files they point to

       -i, --ignore-zeros
              ignore blocks of zeros in  archive  (normally  mean
              EOF)

       -j, --bzip2
              filter  archive  through  bzip2,  use to decompress
              .bz2 files.  WARNING: some previous versions of tar
              used  option  -I  to  filter  through  bzip2.  When
              writing scripts, use --bzip2 instead of -j so  that
              both older and newer tar versions will work.

       --ignore-failed-read
              don't exit with non-zero status on unreadable files

       -k, --keep-old-files
              keep existing  files;  don't  overwrite  them  from
              archive

       -K, --starting-file F
              begin at file F in the archive

       -l, --one-file-system
              stay in local file system when creating an archive

       -L, --tape-length N
              change tapes after writing N*1024 bytes

       -m, --modification-time

              only store files newer than DATE

       -o, --old-archive, --portability
              write a V7 format archive, rather than ANSI format

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

       -p, --same-permissions, --preserve-permissions
              extract all protection information

       -P, --absolute-paths
              don't strip leading `/'s from file names

              create extracted files with the same ownership

       --numeric-owner
              always use numbers for user/group names

       -S, --sparse
              handle sparse files efficiently

       -T, --files-from F
              get names to extract or create from file F

       --null
              -T reads null-terminated names, disable -C

       --totals
              print total bytes written with --create

       -v, --verbose

       --rsh-command=CMD
              Use remote COMMAND instead of `rsh'.   This  option
              exists  so that people who use something other than
              the standard `rsh' (e.g., a Kerberized  `rsh')  can
              access a remote device.

       -[0-7][lmh]
              specify drive and density

BUGS
       The  GNU  folks,  in  general, abhor man pages, and create
       info documents instead.  The maintainer of tar falls  into
       this  category.   This  man  page is neither complete, nor
       current, and was included in the Debian Linux packaging of
       tar  entirely  to reduce the frequency with which the lack
       of a man page gets reported as a bug in our defect  track-
       ing system.

       If  you really want to understand tar, then you should run
       info and read the tar info pages, or use the info mode  in
       emacs.
