xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

xzcmp and
xzdiff invoke
cmp(1) or
diff(1) on files
compressed with
xz(1),
lzma(1),
gzip(1),
bzip2(1),
lzop(1), or
zstd(1). All options specified are passed directly
to
cmp(1) or
diff(1). If only one file is specified, then the
files compared are
file1 (which must have a suffix of a supported
compression format) and
file1 from which the compression format suffix
has been stripped. If two files are specified, then they are uncompressed if
necessary and fed to
cmp(1) or
diff(1). The exit status from
cmp(1) or
diff(1) is preserved unless a decompression error
occurs; then exit status is 2.
The names
lzcmp and
lzdiff are provided for backward compatibility
with LZMA Utils.

Messages from the
cmp(1) or
diff(1) programs refer to temporary
filenames instead of those specified.
