compare compressed files
Compare files, showing the differences side by side
Compare files and report only that they differ (no details on what is different)
Compare files and report when the files are the same
Compare files using paginated results
Compare directories recursively (shows names for differing files/directories as well as changes made to files)
xzcmp [cmp_options] file1
xzdiff [diff_options] file1 [file2]
lzcmp [cmp_options] file1 [file2]
lzdiff [diff_options] file1 [file2]
xzcmp and xzdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(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.
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.
