CSPLIT

csplit − split a file into sections determined by context lines

csplit [OPTION]... FILE PATTERN...

Output pieces of FILE separated by PATTERN(s) to files ‘xx00’, ‘xx01’, ..., and output byte counts of each piece to standard output.

Mandatory arguments to long options are mandatory for short options too.

−b, −−suffix−format=FORMAT

use sprintf FORMAT instead of %02d

−f, −−prefix=PREFIX

use PREFIX instead of ‘xx’

−k, −−keep−files

do not remove output files on errors

−n, −−digits=DIGITS

use specified number of digits instead of 2

−s, −−quiet, −−silent

do not print counts of output file sizes

−z, −−elide−empty−files

remove empty output files

−−help

display this help and exit

−−version

output version information and exit

Read standard input if FILE is −. Each PATTERN may be:

INTEGER

copy up to but not including specified line number

/REGEXP/[OFFSET]

copy up to but not including a matching line

%REGEXP%[OFFSET]

skip to, but not including a matching line

{INTEGER}

repeat the previous pattern specified number of times

{*}

repeat the previous pattern as many times as possible

A line OFFSET is a required ‘+’ or ‘−’ followed by a positive integer.
