.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility reads the given
|
|
.Ar file
|
|
and breaks it up into files of 1000 lines each.
|
|
If
|
|
.Ar file
|
|
is a single dash or absent,
|
|
.Nm
|
|
reads from the standard input.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
Use
|
|
.Ar suffix_length
|
|
letters to form the suffix of the file name.
|
|
.It Fl b
|
|
Create smaller files
|
|
.Ar byte_count
|
|
bytes in length.
|
|
If
|
|
.Ql k
|
|
is appended to the number, the file is split into
|
|
.Ar byte_count
|
|
kilobyte pieces.
|
|
If
|
|
.Ql m
|
|
is appended to the number, the file is split into
|
|
.Ar byte_count
|
|
megabyte pieces.
|
|
.It Fl l
|
|
Create smaller files
|
|
.Ar line_count
|
|
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 using
|
|
.Ar suffix_length
|
|
characters in the range
|
|
.Dq Li a-z .
|
|
If
|
|
.Fl a
|
|
is not specified, two letters are used as the suffix.
|
|
.Pp
|
|
If the
|
|
.Ar name
|
|
argument is not specified,
|
|
.Ql x
|
|
is used.
|
|
.Sh STANDARDS
|
|
The
|
|
.Nm
|
|
utility conforms to
|
|
.St -p1003.1-2001 .
|
|
.Sh HISTORY
|
|
A
|
|
.Nm
|
|
command appeared in
|
|
.At v6 .
|
|
.Pp
|
|
The
|
|
.Fl a
|
|
option was introduced in
|
|
.Nx 2.0 .
|
|
Before that, if
|
|
.Ar name
|
|
was not specified,
|
|
.Nm
|
|
would vary the first letter of the filename
|
|
to increase the number of possible output files.
|
|
The
|
|
.Fl a
|
|
option makes this unnecessary.
