and breaks it up into files of 1000 lines each.

The options are as follows:
.Bl -tag -width Ds
.It Fl b
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
Create smaller files
.Ar n
lines in length.
.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 in the range of 
.Dq Li aa-zz .
.Pp
If the
.Ar name
argument is not specified, the file is split into lexically ordered
files named in the range of
