TARSPLIT(1)                                           TARSPLIT(1)

     NAME
          tarsplit, tarcat - split a tar archive into archives under
          some size, or combine archives

     SYNOPSIS
          tarsplit [ -p prefix ] [ -s size ] [ file ...  ]

          tarcat [ file ...  ]

     DESCRIPTION
          Tarsplit copies a tar(1) archive from input file(s) into a
          series of independent tar archives with names starting with
          prefix (`ts.' by default) and no larger than a fixed size
          (512MB by default).  This can be useful when copying large
          archives onto fixed-size storage media such as CDs or DVDs.

          Tarsplit prints a list on standard output of the resulting
          archive names, and the first and last member names in each,
          to assist finding particular members without recombining the
          archives.

          Tarcat copies tar(1) archives from input files and combines
          them into a single tar archive.  It is the inverse of
          tarsplit.

     EXAMPLES
          Archive /adm and split the result.

               ; tar c /adm | tarsplit -s 409600
               ts.00000: /adm/ ... /adm/brickdb/have/timeout/viaduct60
               ts.00001: /adm/brickdb/have/tls-log ... /adm/timezone/Australia_ACT
               ts.00002: /adm/timezone/Australia_Broken-Hill ... /adm/words
               ; file ts.*
               ts.00000: posix tar archive
               ts.00001: posix tar archive
               ts.00002: posix tar archive

          Reassemble the original archive and check the tail end for
          completeness:

               ; tarcat ts.* | tar t | tail -2
               ./adm/whois
               ./adm/words
