Does anyone have a script to check for circular symbolic links? I had some lately that I noticed things like /foo/bar/bar -> /foo/bar. I think they got created by a script I had to go fix some of the symbolic links on the system (the script probably got a little over ambitious). I can generate something with the "symlink -> file" stuff in it, but need to know a good way to check for symbolic links into the same directory. It seems I only need to check on things if the "file" is a directory. The simpler case is checking to see if a particular symlink loops back into its own directory path. That could probably be checked by getting the device/inode #s for each directory in the "file"s path and comparing with the device/inode # of the parent directory of the "symlink". This would take care of this particular mistake, but a more general solution should check for multiple jump cycles... /a/b/c/d -> /e/f/g -> /h/i/j -> /a/b Anybody have anything?
