    Only as much as the design of the script allows.
Properly-filtered code (including using escapeshellarg() and
escapeshellcmd()) should work fine.  Maybe a simple regexp to only
accept /(^[a-z0-9\s-_\.]*$)/i (untested) would be in order as well.  I
do agree that it shouldn't be used as a replacement for anything that
can be done natively in PHP, but there are situations where using a
PHP-only system is impractical and imprudent.
