- All options specified are passed directly to

- (which must have a suffix of a supported compression format) and

- from which the compression format suffix has been stripped.

- then they are uncompressed if necessary and fed to
- .BR cmp (1)
- or

- The exit status from
- .BR cmp (1)
- or
- .BR diff (1)
- is preserved unless a decompression error occurs; then exit status is 2.
