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.

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 /dev/rmt0)

       --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, -I, --bzip
              filter the archive through bzip2. Note: -I is deprecated and may
              get a different meaning in the near future.

       --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
              don't extract file modified time

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

       -N, --after-date DATE, --newer DATE
              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

       --preserve
              like -p -s

       -R, --record-number
              show record number within archive with each message

       --remove-files
              remove files after adding them to the archive
