bzcmp, bzdiff - compare bzip2 compressed files

# [SYNOPSIS](#SYNOPSIS)

**bzcmp** \[ cmp\_options ] file1 \[ file2 ]  
**bzdiff** \[ diff\_options ] file1 \[ file2 ]

# [DESCRIPTION](#DESCRIPTION)

*Bzcmp* and *bzdiff* are used to invoke the *cmp* or the *diff* program on bzip2 compressed files. All options specified are passed directly to *cmp* or *diff*. If only 1 file is specified, then the files compared are *file1* and an uncompressed *file1*.bz2. If two files are specified, then they are uncompressed if necessary and fed to *cmp* or *diff*. The exit status from *cmp* or *diff* is preserved.
