SPLIT(1)			   BSD General Commands Manual				 SPLIT(1)

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      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 num-
	     ber, 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.

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
     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.
