Thanks Wietse. The external commands are all Perl scripts, and I'm only really interested if they have a bad exit status. Therefore, the best thing might be to do something similar to the above, but log the error somewhere that I will notice it (or maybe even use a Perl "wrapper" script that deals with any exceptions)? Thanks, Andy
