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

| .BR cmp (1) | |
| or | |
| .BR diff (1) | |
| programs refer to temporary filenames instead of those specified. | |
