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
 output version information and exit
Read standard input if FILE is -. Each PATTERN may be:
 copy up to but not including specified line number
 copy up to but not including a matching line
 skip to, but not including a matching line
 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.
