Warning. The -w option will give you a misleading postive result in the case where you have permissions, but the partition is mounted read-only (popular for NFS on unix). We actually just wrote a quick function to test writeability by opening a file for write access wherever we were checking, and, if successful, deleting it afterwards. It was the only foolproof way we could come up with of detecting the situation.
