Create/list/extract multi‐volume archive.

       --rmt-command=COMMAND
              Use COMMAND instead of rmt when accessing remote archives.  See the description of the -f option, above.

       --rsh-command=COMMAND
              Use COMMAND instead of rsh when accessing remote archives.  See the description of the -f option, above.

       --volno-file=FILE
              When this option is used in conjunction with --multi-volume, tar will keep track of which volume of a multi‐volume archive it is working in FILE.

   Device blocking
       -b, --blocking-factor=BLOCKS
              Set record size to BLOCKSx512 bytes.

       -B, --read-full-records
              When listing or extracting, accept incomplete input records after end‐of‐file marker.

       -i, --ignore-zeros
              Ignore  zeroed  blocks  in  archive.   Normally two consecutive 512‐blocks filled with zeroes mean EOF and tar stops reading after encountering them.  This option instructs it to read further and is useful when
              reading archives created with the -A option.

       --record-size=NUMBER
              Set record size.  NUMBER is the number of bytes per record.  It must be multiple of 512.  It can can be suffixed with a size suffix, e.g. --record‐size=10K, for 10 Kilobytes.  See the subsection Size  suffixes,
              for a list of valid suffixes.

   Archive format selection
       -H, --format=FORMAT
              Create archive of the given format.  Valid formats are:

              gnu    GNU tar 1.13.x format

              oldgnu GNU format as per tar <= 1.12.

              pax, posix
                     POSIX 1003.1‐2001 (pax) format.

              ustar  POSIX 1003.1‐1988 (ustar) format.

              v7     Old V7 tar format.

       --old-archive, --portability
              Same as --format=v7.

       --pax-option=keyword[[:]=value][,keyword[[:]=value]]...
              Control pax keywords when creating PAX archives (-H pax).  This option is equivalent to the -o option of the pax(1) utility.

       --posix
              Same as --format=posix.

       -V, --label=TEXT
              Create archive with volume name TEXT.  If listing or extracting, use TEXT as a globbing pattern for volume name.

   Compression options
       -a, --auto-compress
              Use archive suffix to determine the compression program.

       -I, --use-compress-program=COMMAND
              Filter data through COMMAND.  It must accept the -d option, for decompression.  The argument can contain command line options.

       -j, --bzip2
              Filter the archive through bzip2(1).

       -J, --xz
              Filter the archive through xz(1).

       --lzip Filter the archive through lzip(1).

       --lzma Filter the archive through lzma(1).

       --lzop Filter the archive through lzop(1).

       --no-auto-compress
              Do not use archive suffix to determine the compression program.

       -z, --gzip, --gunzip, --ungzip
              Filter the archive through gzip(1).

       -Z, --compress, --uncompress
              Filter the archive through compress(1).

       --zstd Filter the archive through zstd(1).

   Local file selection
       --add-file=FILE
              Add FILE to the archive (useful if its name starts with a dash).

       --backup[=CONTROL]
              Backup before removal.  The CONTROL argument, if supplied, controls the backup policy.  Its valid values are:

              none, off
                     Never make backups.

              t, numbered
                     Make numbered backups.

              nil, existing
                     Make numbered backups if numbered backups exist, simple backups otherwise.

              never, simple
                     Always make simple backups

              If CONTROL is not given, the value is taken from the VERSION_CONTROL environment variable.  If it is not set, existing is assumed.

       -C, --directory=DIR
              Change to
