Recover a corrupted gz

Sometimes you might be able to salvage a corrupted gzip. Typically this trick always works on most log files.
$ gunzip corrupted.gz
gunzip: corrupted.gz: unexpected end of file
gunzip: corrupted.gz: uncompress failed
Use the -c option that outputs to console, but redirect to a new salvaged file. Then gzip the salvaged file to recover it.
$ gunzip -c corrupted.gz > salvaged
$ gzip salvaged
You can now delete the corrupted gz file and use the salvaged version.
