csplit
CSPLIT(1) BSD General Commands Manual CSPLIT(1)NAME
csplit -- split files based on context
SYNOPSIS
csplit [-ks] [-f prefix] [-n number] file args ...
DESCRIPTION
The csplit utility splits file into pieces using the patterns args. If file is a dash ('-'), csplit reads from standard input.
Files are created with a prefix of ``xx'' and two decimal digits. The size of each file is written to standard output as it is created. If
an error occurs whilst files are being created, or a HUP, INT, or TERM signal is received, all files previously written are removed.
The options are as follows:
-f prefix Create file names beginning with prefix, instead of ``xx''.
-k Do not remove previously created files if an error occurs or a HUP, INT, or TERM signal is received.
-n number Create file names beginning with number of decimal digits after the prefix, instead of 2.
-s Do not write the size of each output file to standard output as it is created.
The args operands may be a combination of the following patterns:
/regexp/[[+|-]offset]
Create a file containing the input from the current line to (but not including) the next line matching the given basic reg-
ular expression. An optional offset from the line that matched may be specified.
%regexp%[[+|-]offset]
Same as above but a file is not created for the output.
line_no Create containing the input from the current line to (but not including) the specified line number.
{num} Repeat the previous pattern the specified number of times. If it follows a line number pattern, a new file will be created
for each line_no lines, num times. The first line of the file is line number 1 for historic reasons.
After all the patterns have been processed, the remaining input data (if there is any) will be written to a new file.
Requesting to split at a line before the current line number or past the end of the file will result in an error.
The csplit utility exits 0 on success, and >0 if an error occurs.
ENVIRONMENT
The LANG, LC_ALL, LC_COLLATE, and LC_CTYPE environment variables affect the execution of csplit as described in environ(7).
EXAMPLES
Split the mdoc(7) file foo.1 into one file for each section (up to 20):
$ csplit -k foo.1 '%^.Sh%' '/^.Sh/' '{20}'
Split standard input after the first 99 lines and every 100 lines thereafter:
$ csplit -k - 100 '{19}'
SEE ALSO sed(1), split(1), re_format(7)STANDARDS
The csplit utility conforms to IEEE Std 1003.1-2004 (``POSIX.1'').
HISTORY
A csplit command appeared in PWB UNIX.
BUGS
Input lines are limited to LINE_MAX (2048) bytes in length.
