I'm looking for a way to search through an entire filesystem verifying file validity where possible.

That is, if the file is a known file type that can be consistency checked, then run that check and see if it passes. So for a .zip file (including .jar, .odt, etc) run it through "unzip -t". And so on for other file types.

I can't think of a suitable Google search that doesn't just throw up file system consistency checks, or tests against previously stored md5sum data (which I don't have, but wouldn't really be what I wanted anyway).

I'll look at scripting something otherwise, but I'm not a wheel inventor if I can help it.

On the assumption nobody has a good solution, the next best thing would be as many helpful hints as to file types I can test for consistency and what tools to test them with.
