NAME    [Toc]    [Back]

     split -- split a file into pieces

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

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

     -b      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      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 specified,
     two letters are used as the suffix.

     If the name argument is not specified, the file is split into lexically
     ordered files named with prefixes in the range of ``x-z'' and with suffixes
 as above.

SEE ALSO    [Toc]    [Back]

     csplit(1), re_format(7)

STANDARDS    [Toc]    [Back]

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

HISTORY    [Toc]    [Back]

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

BUGS    [Toc]    [Back]

     For historical reasons, if you specify name, split can only create 676
     separate files.  The default naming convention allows 2028 separate
     files.  The -a option can be used to work around this limitation.

     The maximum line length for matching patterns is 65536.
