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 .RL ( 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 file s and combines them into a single tar archive. It is the inverse of tarsplit .
EXAMPLES
Archive
/adm and split the result.
.EX
; 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:
.EX ; tarcat ts.* | tar t | tail -2 ./adm/whois ./adm/words FILES
prefixNNNNN output archives
