.Nm

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility reads the given
|
|
.Ar file
|
|
(or standard input if no file is specified)
|
|
and breaks it up into files of 1000 lines each.
|
|
.Pp
|
|
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.
|
|
.It Fl p Ar pattern
|
|
The file is split whenever an input line matches
|
|
.Ar pattern ,
|
|
which is interpreted as an extended regular expression.
|
|
The matching line will be the first line of the next output file.
|
|
This option is incompatible with the
|
|
.Fl b
|
|
and
|
|
.Fl l
|
|
options.
|
|
.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
|
|
.Dq Li xaa-zzz .
|
|
.Sh BUGS
|
|
For historical reasons, if you specify
|
|
.Ar name ,
|
|
.Nm
|
|
can only create 676 separate
|
|
files.
|
|
The default naming convention allows 2028 separate files.
|
|
.Pp
|
|
The maximum line length for matching patterns is 65536.
