53: The
1.5 aaron 54: .Nm
1.1 deraadt 55: utility reads the given
1.11 jmc 56: .Ar file ,
57: or standard input if no file is specified,
58: and breaks it up into files of 1000 lines each.
1.1 deraadt 59: .Ar file
1.11 jmc 60: itself is not altered.
1.1 deraadt 61: .Pp
62: The options are as follows:
63: .Bl -tag -width Ds
1.12 millert 64: .It Fl a Ar suffix_length
65: Use
66: .Ar suffix_length
67: letters to form the suffix of the file name
68: (see below).
69: The default suffix length is 2.

80: If
1.5 aaron 81: .Sq k
1.1 deraadt 82: is appended to the number, the file is split into
83: .Ar byte_count
84: kilobyte pieces.
85: If
1.5 aaron 86: .Sq m
1.1 deraadt 87: is appended to the number, the file is split into
88: .Ar byte_count
89: megabyte pieces.

1.17 jmc 91: Create files
1.10 jmc 92: .Ar line_count
1.1 deraadt 93: lines in length.
1.3 millert 94: .It Fl p Ar pattern
95: The file is split whenever an input line matches
96: .Ar pattern ,
97: which is interpreted as an extended regular expression.
98: The matching line will be the first line of the next output file.
1.12 millert 99: This option is incompatible with the
100: .Fl b
101: and
102: .Fl l
103: options.

105: .Pp
1.11 jmc 106: If
107: .Ar name
108: is specified,
109: it is used as a prefix
1.1 deraadt 110: for the names of the files into which the file is split.
111: In this case, each file into which the file is split is named by the
1.12 millert 112: prefix followed by a lexically ordered suffix using
113: .Ar suffix_length
114: characters in the range
115: .Dq a-z .
116: .Pp
1.1 deraadt 117: If the
118: .Ar name
119: argument is not specified, the file is split into lexically ordered
1.12 millert 120: files named with the prefixes
1.13 jmc 121: .Sq x ,
122: .Sq y ,
1.12 millert 123: and

131: The
132: .Nm
133: utility is compliant with the
1.18 jmc 134: .St -p1003.1-2008
1.12 millert 135: specification.
1.15 jmc 136: .Pp
137: The flag
138: .Op Fl p
139: is an extension to that specification.

141: The use of
1.13 jmc 142: .Sq y
1.12 millert 143: and
1.13 jmc 144: .Sq z
1.12 millert 145: prefixes (in addition to the standard
1.13 jmc 146: .Sq x )
1.12 millert 147: in the absence of a
