42: .Op Fl l Ar line_count
1.3 millert 43: .Op Fl p Ar pattern
1.1 deraadt 44: .Op Ar file Op Ar name
45: .Sh DESCRIPTION
46: The
1.5 aaron 47: .Nm
1.1 deraadt 48: utility reads the given
49: .Ar file
50: (or standard input if no file is specified)
51: and breaks it up into files of 1000 lines each.
52: .Pp
53: The options are as follows:
54: .Bl -tag -width Ds
55: .It Fl b
56: Create smaller files
57: .Ar byte_count
58: bytes in length.
59: If
1.5 aaron 60: .Sq k
1.1 deraadt 61: is appended to the number, the file is split into
62: .Ar byte_count
63: kilobyte pieces.
64: If
1.5 aaron 65: .Sq m
1.1 deraadt 66: is appended to the number, the file is split into
67: .Ar byte_count
68: megabyte pieces.
69: .It Fl l
70: Create smaller files
71: .Ar n
72: lines in length.
1.3 millert 73: .It Fl p Ar pattern
74: The file is split whenever an input line matches
75: .Ar pattern ,
76: which is interpreted as an extended regular expression.
77: The matching line will be the first line of the next output file.
78: This option is incompatible with the
79: .Fl b
80: and
81: .Fl l
82: options.
1.1 deraadt 83: .El
84: .Pp
85: If additional arguments are specified, the first is used as the name
86: of the input file which is to be split.
87: If a second additional argument is specified, it is used as a prefix
88: for the names of the files into which the file is split.
89: In this case, each file into which the file is split is named by the
1.4 aaron 90: prefix followed by a lexically ordered suffix in the range of
1.5 aaron 91: .Dq aa-zz .
1.1 deraadt 92: .Pp
93: If the
94: .Ar name
95: argument is not specified, the file is split into lexically ordered
96: files named in the range of
1.5 aaron 97: .Dq xaa-zzz .

106: For historical reasons, if you specify
107: .Ar name ,
1.5 aaron 108: .Nm
1.1 deraadt 109: can only create 676 separate
110: files.
111: The default naming convention allows 2028 separate files.
1.3 millert 112: .Pp
113: The maximum line length for matching patterns is 65536.
