- Compare files:
xzdiff path/to/file1 path/to/file2
- Compare files, showing the differences side by side:
xzdiff --side-by-side path/to/file1 path/to/file2
- Compare files and report only that they differ (no details on what is different):
xzdiff --brief path/to/file1 path/to/file2
- Compare files and report when the files are the same:
xzdiff --report-identical-files path/to/file1 path/to/file2
- Compare files using paginated results:
xzdiff --paginate path/to/file1 path/to/file2
xzcmp [cmp_options] file1 [file2]
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), 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.
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zstd(1), zdiff(1)
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
The man pages lzcmp(1), lzdiff(1) and xzcmp(1) are aliases of xzdiff(1).
