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 kilo-
             byte 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 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 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.

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.
