                     53: .Ar file
                     54: (or standard input if no file is specified)
                     55: and breaks it up into files of 1000 lines each.
                     56: .Pp
                     57: The options are as follows:
                     58: .Bl -tag -width Ds
                     59: .It Fl b
                     60: Create smaller files
                     61: .Ar byte_count
                     62: bytes in length.
                     63: If
1.5     ! aaron      64: .Sq k
1.1       deraadt    65: is appended to the number, the file is split into
                     66: .Ar byte_count
                     67: kilobyte pieces.
                     68: If
1.5     ! aaron      69: .Sq m
1.1       deraadt    70: is appended to the number, the file is split into
                     71: .Ar byte_count
                     72: megabyte pieces.
                     73: .It Fl l
                     74: Create smaller files
                     75: .Ar n
                     76: lines in length.
1.3       millert    77: .It Fl p Ar pattern
                     78: The file is split whenever an input line matches
                     79: .Ar pattern ,
                     80: which is interpreted as an extended regular expression.
                     81: The matching line will be the first line of the next output file.
                     82: This option is incompatible with the
                     83: .Fl b
                     84: and
                     85: .Fl l
                     86: options.

                     88: .Pp
                     89: If additional arguments are specified, the first is used as the name
                     90: of the input file which is to be split.
                     91: If a second additional argument is specified, it is used as a prefix
                     92: for the names of the files into which the file is split.
                     93: In this case, each file into which the file is split is named by the
1.4       aaron      94: prefix followed by a lexically ordered suffix in the range of
1.5     ! aaron      95: .Dq aa-zz .
1.1       deraadt    96: .Pp
                     97: If the
                     98: .Ar name
                     99: argument is not specified, the file is split into lexically ordered
                    100: files named in the range of
