If you can make sure the script runs under taint mode
(it isn't just for CGIs!), then you've taken a significant

(-T on the command or '#!' line) isn't a magic bullet,
though. It can stop you from making some subtle mistakes, like using
unexamined user input in eval or system (not just system) calls.
