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
