If .Ar file is a single dash .Pq Sq Fl or absent, .Nm reads from the standard input. .Pp The options are as follows: .Bl -tag -width Ds .It Fl a Ar suffix_length Use .Ar suffix_length letters to form the suffix of the file name. .It Fl b Ar byte_count[k|m] Create smaller files .Ar byte_count bytes in length. If .Dq Li k is appended to the number, the file is split into .Ar byte_count kilobyte pieces. If .Dq Li m is appended to the number, the file is split into .Ar byte_count megabyte pieces. .It Fl l Ar line_count Create smaller files .Ar n lines in length. .It Fl p Ar pattern The file is split whenever an input line matches .Ar 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 .Fl b and .Fl l options. .El .Pp 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 .Ar suffix_length characters in the range .Dq Li a-z . If .Fl a is not specified, two letters are used as the suffix. .Pp If the .Ar name argument is not specified, the file is split into lexically ordered files named with the prefix .Dq Li x and with suffixes as above. .Sh ENVIRONMENT The .Ev LANG , LC_ALL , LC_CTYPE and .Ev LC_COLLATE environment variables affect the execution of .Nm as described in .Xr environ 7 . .Sh EXIT STATUS .Ex -std .Sh SEE ALSO .Xr csplit 1 , .Xr re_format 7 .Sh STANDARDS The .Nm utility conforms to .St -p1003.1-2001 . .Sh HISTORY A .Nm command appeared in .At v3 . .Sh BUGS The maximum line length for matching patterns is 65536.
