Actually, I realized that the algorithm I posted may not be safe enough. It probably has the same race conditions as the traditional "find | xargs" solution, but if for each file you kept: path timestamp creation-date inode and refused to delete anything whose inode number (or creation date if the inode is the same) had changed since you last looked, would that be safe? Is there any way to atomically get the inode number/creation date and delete the file after checking it? Not being a security expert, I should probably shut up now. -- Rob Browning <[EMAIL PROTECTED]> PGP fingerprint = E8 0E 0D 04 F5 21 A0 94 53 2B 97 F5 D6 4E 39 30 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
