zcmp, zdiff - compare compressed files
zcmp [options] file [file2]
zdiff [options] file [file2]
zcmp and zdiff are filters that invoke cmp(1) or diff(1) respectively to
compare compressed files. Such files generally have a ``Z''
extension (both the compress(1) and gzip(1) formats are supported). Any
options that are specified are passed to cmp(1) or diff(1).
If only file1 is specified, it is compared against a file
with the same
name, but with the extension removed. When both file1 or
file2 are specified,
either file may be compressed.
TMPDIR Directory in which to place temporary files. If unset, /tmp is
/tmp/zcmp.XXXXXXXXXX Temporary file for zcmp.
/tmp/zdiff.XXXXXXXXXX Temporary file for zdiff.
cmp(1), compress(1), diff(1)
zcmp and zdiff rely solely on the file extension to determine what is, or
is not, a compressed file. Consequently, the following are
- device special files
- filenames indicating the standard input (``-'')
