TOCTOU, but why? unlink() won't kill your grandma if the file to be deleted does not exist (any more). It will just generate an error ("No such file or directory"). It also generates an error ("Is a directory") when you attempt to delete a directory instead of a plain file (unless you are root, have started perl with the -U flag, and your OS supports unlinking a directory). So, unlink(), check $!, TOCTOU problem gone. Alexander
