     csplit -- split files based on context

     csplit [-ks] [-f prefix] [-n number] file args ...

     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 sig-
     nal is received, all files previously written are removed.

     The options are as follows:

           -f prefix   Create file names beginning with prefix, instead of

           -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 dig-
                       its 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:

                       Create a file containing the input from the current
                       line to (but not including) the next line matching the
                       given basic regular expression.  An optional offset
                       from the line that matched may be specified.

                       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

     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.

     The LANG, LC_ALL, LC_COLLATE, and LC_CTYPE environment variables affect
     the execution of csplit as described in environ(7).

     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 there-

           $ csplit -k - 100 '{19}'

     sed(1), split(1), re_format(7)

     The csplit utility conforms to IEEE Std 1003.1-2004 (``POSIX.1'').

     A csplit command appeared in PWB UNIX.

     Input lines are limited to LINE_MAX (2048) bytes in length.
