CompressMissingFiles.sh for *nix servers

[Barbie]

Just a simple shell script that checks if all available files also exist in the redirect folder for compressed files and compresses them, if not there. It also checks the other way round if there are compressed files that have no uncompressed equivalent and print their names. I have this running for months now without problems. Maybe it helps someone.
