Re: How to trap !sh at keyboard

It seems that some of our users are inclined to key in '!sh' at the shell prompt, which promptly shuts down our Red Hat Enterprise 3 Server, interrupting everyone else's work. Is there a line that we can add to the inittab file, that will trap this string, in the same fashion that the 'ca::ctrlaltdel:/sbin/shutdown -t3 -r now' line traps Ctrl-Alt-Delete inputs?

Haha, is this a joke to get people to try it out and shut down their machines? I actually tried it on a test-host, not believing you and not realizing that it would execute the last command that began with sh, which did happen to be 'shutdown -r now'.

Thanks for the laugh on a Friday afternoon :)
