If this is a multi-user system, you don't want to do this any time except when it's in single-user (like, say, during boot) because it creates a huge race condition. (If I know that you run this once a day at a specific time because I sit and watch top or whatever, then I can find a way to trick you into deleting the wrong thing. Like /etc/passwd. Or a random .htaccess file. So forth.) The danger's a bit less if you don't do it as root, but only root will be able to rm everything in [/var]/tmp with default permissions (because of the sticky bit). -- gabriel rosenkoetter gr@eclipsed.net Attachment:
