xzcmp(1) - Linux man page
Name
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
Synopsis
xzcmp [cmp_options] file1 [file2]
xzdiff [diff_options] file1 [file2]
lzcmp [cmp_options] file1 [file2]
lzdiff [diff_options] file1 [file2]
Description
xzcmp and xdiff invoke cmp(1) or diff(1) on files compressed
with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed directly to cmp or
diff. 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 or diff is preserved.
The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

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