    Given the responses I received from people, I now realize that I
should have been more clear.
    I want to know if there is any way to pass shell metacharacters
through the $temp_file variable in such a way that would pass the "-e"
check but still make it to the open() call.  Of course, lets forget that my
example uses "<", because this prevents "|" from working.
    I already tried inserting nulls here and there, but without success.
