xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

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), 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.

*cmp*(1), *diff*(1), *xz*(1), *gzip*(1), *bzip2*(1), *lzop*(1), *zdiff*(1)

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