SPLIT(1) OpenBSD Reference Manual SPLIT(1)NAMEsplit - split a file into pieces
SYNOPSISsplit [-a suffix_length]
[-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. file itself
is not altered.
The options are as follows:
-a suffix_length
Use suffix_length letters to form the suffix of the file name
(see below). The default suffix length is 2.
-b byte_count[k|m]
Create 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 files line_count 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 name 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 the name argument is not specified, the file is split into lexically
ordered files named with the prefixes `x', `y', and `z'.
EXIT STATUS
The split utility exits 0 on success, and >0 if an error occurs.
SEE ALSOcsplit(1), re_format(7)STANDARDS
The split utility is compliant with the IEEE Std 1003.1-2008 (``POSIX'')
specification.
The flag [-p] is an extension to that specification.
The use of `y' and `z' prefixes (in addition to the standard `x') in the
absence of a name parameter is an OpenBSD extension.
HISTORY
A split command appeared in Version 3 AT&T UNIX.
BUGS
The maximum line length for matching patterns is 65536.
