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 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 complete‐
ness:
