I need to be able to execute a shell command if a mysql query is successful.

(i know of the command system() )

background:

slackware box, running mysql and apache, has no keyboard or mouse, or monitor (input is strickly barcode scanner) if the scan is sucessfull i need to print a file directly to a parallel printer attached to the server if it is unsucsessful i need the computer to beep (\a command which DOES not work for me!!!!!)

Please help!!!!

\a probably doesn't work in your case, because \a causes beep on the client-end when there is a tty attached.

Use beep instead.

Here is the code from my php page, lynx is not running as root.

exec('/usr/bin/beep');

but will not beep when executed.
beep DOES work running as root from console,
running as another user (loged out and back in ) i get "could not open /dev/console for writing"

any advice?????

Is the php scrip on the same pc as you are accessing the page from?

See the README that was with the software.

(the beep has to be set suid-root)
