Yikes!  What a security problem waiting to happen.

But it isn't hard to write better shell scripts in terms of
security, as long as you know the issues.

  First: Stop symlink attacks.
         Create an owned temporary directory, that only
         the shell user can write to.  

         This stops someone from being able to create a
         symlink to a file they want truncated.

  Second: Consider that more than one message may be in
          processing at a time.  So append the PID to the
          temp filenames to handle that case.  Generally
          the PID is available in the shell as $$.

It will only take you a few minutes to make these
adaptations and test them.  Post it back to the list
when you are done, since someone else may be interested
in what you are doing.  Thanks for posting.
