Micah Gersten schreef: You can rename the php executable and replace it with a shell script that logs what is run. true, but that still wouldn't get me the pipe, besides which one day someone will figure out that it's not the actual executable and either: 1. recompile and install php (shell script overwritten) 2. start using the actual binary instead in both cases they'd probably think they're doing something smart :-) which is why it would be nice to do it from with in my own script without tweaking/hacking anything on the system. it's then self contained and because I deliver the script I control it's functionality of course the script could be edited, but if a 3rd party or the client does *that* then I'm no longer responsible ... currently I'm not responsible for the system/server itself (although I have full access) and I'd like to keep it that way ... sysadmin is a special kind of beast, I'm of another genus :) Thank you, Micah Gersten onShore Networks Internal Developer http://www.onshore.com Jochem Maas wrote: David Otton schreef: Quote the entire command as a string.

Only do it that way if it's for a log of general output. If you're going
to punt any of those parts back to the OS in another command you'll need
to properly escape them.
