    You should always use the absolute paths to invoke commands in any script
    run by root. This prevents people from putting "trojans" in the path
    and it will also solve the problem you are experiencing.

    for example
    use "/bin/cp" for cp
    use "/bin/rm" for rm.

    As a practical matter almost no one uses the "only invoke commands by
    absolute path" approach. Its too cumbersome.

    But the absolute path approach will fix the problem of invoking aliases
    rather than the actual commands. And it doesn't break when no aliases
    are defined.
