| 26 and |
| 27 .B xzdiff |
| 28 invoke |
| 29 .BR cmp (1) |
| 30 or |
| 31 .BR diff (1) |
| 32 on files compressed with |
| 33 .BR xz (1), |
| 34 .BR lzma (1), |
| 35 .BR gzip (1), |
| 36 or |

| 42 If only one file is specified, then the files compared are |
| 43 .I file1 |
| 44 (which must have a suffix of a supported compression format) and |
| 45 .I file1 |
| 46 from which the compression format suffix has been stripped. |
| 47 If two files are specified, then they are uncompressed if necessary and fed to |
| 48 .BR cmp (1) |
| 49 or |
| 50 .BR diff (1). |
| 51 The exit status from |
| 52 .B cmp |
| 53 or |
