.Sh DESCRIPTION
|
|
.Nm zcmp
|
|
and
|
|
.Nm zdiff
|
|
are filters that invoke
|
|
.Xr cmp 1
|
|
or
|
|
.Xr diff 1
|
|
respectively to compare compressed files.
|
|
Any
|
|
.Ar options
|
|
that are specified are passed to
|
|
.Xr cmp 1
|
|
or
|
|
.Xr diff 1 .
|
|
.Pp
|
|
If only
|
|
.Ar file1
|
|
is specified, it is compared against a file with the same name, but
|
|
with the extension removed.
|
|
When both
|
|
.Ar file1
|
|
or
|
|
.Ar file2
|
|
are specified, either file may be compressed.

.Sh CAVEATS
|
|
.Nm zcmp
|
|
and
|
|
.Nm zdiff
|
|
rely solely on the file extension to determine what is, or is not,
|
|
a compressed file.
|
|
