NAME

split - split a file into pieces

SYNOPSIS

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

DESCRIPTION

The split utility reads the given file (or standard input if no file is specified) and breaks it up into files of 1000 lines each.

OPTIONS

split accepts the following options:

-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[k|m]

Create smaller files line_count lines in length. ``k'' and ``m'' operate as with -b.

-p pattern

The file is split whenever an input line matches pattern, which is interpreted as a Perl 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 in the range of ``aaa-zzz''.

If the name argument is not specified, the file is split into lexically ordered files named in the range of ``xaaa-xzzz''.

BUGS

split can only create 17576 files.
