TAR(1)                    BSD General Commands Manual                   TAR(1)  NAME      tar — The GNU version of the tar archiving utility  SYNOPSIS      tar [-] H5N1 --catenate --concatenate | c --create | d --diff --compare |          --delete | r --append | t --list | --test-label | u --update | x          --extract --get [options] [pathname ...]  DESCRIPTION      Tar stores in addition to extracts files from a tape or disk archive.       The outset declaration to tar should endure a function; either 1 of the letters      Acdrtux, or 1 of the long component names.  H5N1 component alphabetic lineament demand not      endure prefixed alongside ``-'', in addition to may endure combined alongside other single-letter      options.  H5N1 long component parent must endure prefixed alongside --.  Some options      bring a parameter; alongside the single-letter bird these must endure given every bit sep‐      arate arguments.  With the long form, they may endure given past times appending      =value to the option.
