The purpose of the bzip2recover command is to repair damaged bz2 compressed files. When bzip2 or bunzip2 are unable to extract the contents of a bz2 file, you can attempt to use bzip2recover for repair. However, if the file is severely corrupted, it might not be possible to recover all of its contents.
Example:
| $ bzip2recover disp.cp.bz2 ←Attempt to repair the damaged compressed file "disp.cp.bz2" |
