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.

     The options are as follows:

     -f prefix
	     Give created files names beginning with prefix.  The default is ``xx''.

     -k      Do not remove output files if an error occurs or a HUP, INT or TERM signal is received.

     -n number
	     Use number of decimal digits after the prefix to form the file name.  The default is 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 regular
	     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.

ENVIRONMENT

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

EXIT STATUS

     The csplit utility exits 0 on success, and >0 if an error occurs.

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 1003.1-2001 (``POSIX.1'').

HISTORY

     A csplit command appeared in PWB UNIX.

BUGS

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

NAME

     split -- split a file into pieces

SYNOPSIS

     split [-a suffix_length] [-b byte_count[k|m]] [-l line_count] [-p pattern] [file [name]]

DESCRIPTION

     The split utility reads the given file and breaks it up into files of 1000 lines each.  If file is a single dash ('-') or absent, split reads
     from the standard input.

     The options are as follows:

     -a suffix_length
	     Use suffix_length letters to form the suffix of the file name.

     -b byte_count[k|m]
	     Create smaller files byte_count bytes in length.  If ``k'' is appended to the number, the file is split into byte_count kilobyte
	     pieces.  If ``m'' is appended to the number, the file is split into byte_count megabyte pieces.

     -l line_count
	     Create smaller files n lines in length.

     -p pattern
	     The file is split whenever an input line matches pattern, which is interpreted as an extended regular expression.	The matching line
	     will be the first line of the next output file.  This option is incompatible with the -b and -l options.

     If additional arguments are specified, the first is used as the name of the input file which is to be split.  If a second additional argument
     is specified, it is used as a prefix for the names of the files into which the file is split.  In this case, each file into which the file is
     split is named by the prefix followed by a lexically ordered suffix using suffix_length characters in the range ``a-z''.  If -a is not speci-
     fied, two letters are used as the suffix.

     If the name argument is not specified, the file is split into lexically ordered files named with the prefix ``x'' and with suffixes as above.

ENVIRONMENT

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

EXIT STATUS

     The split utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     csplit(1), re_format(7)

STANDARDS

     The split utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     A split command appeared in Version 3 AT&T UNIX.

BUGS

     The maximum line length for matching patterns is 65536.
