45.Sh DESCRIPTION
46The
47.Nm split
48utility reads the given
49.Ar file
50(or standard input if no file is specified)
51and breaks it up into files of 1000 lines each.

54.Bl -tag -width Ds
55.It Fl b
56Create smaller files
57.Ar byte_count
58bytes in length.
59If
60.Dq Li k
61is appended to the number, the file is split into
62.Ar byte_count
63kilobyte pieces.
64If
65.Dq Li m
66is appended to the number, the file is split into
67.Ar byte_count
68megabyte pieces.
69.It Fl l
70Create smaller files
71.Ar n
72lines in length.
73.El
74.Pp
75If additional arguments are specified, the first is used as the name
76of the input file which is to be split.
77If a second additional argument is specified, it is used as a prefix
78for the names of the files into which the file is split.
79In this case, each file into which the file is split is named by the
80prefix followed by a lexically ordered suffix in the range of
81.Dq Li aa-zz .
82.Pp
83If the
84.Ar name
85argument is not specified, the file is split into lexically ordered
86files named in the range of
87.Dq Li xaa-zzz .
88.Sh BUGS
89For historical reasons, if you specify
90.Ar name ,
91.Nm split
92can only create 676 separate
93files.
94The default naming convention allows 2028 separate files.
