It's called "security". You're not supposed to be able to kill somebody else's processes. If it's something you must do from a non-priviledged account: be very, very careful. A couple of ways of doing this are sudo and setuid, but as I said, be very, very careful - what if someone else were to run this program? rdfield	[reply]

Well, duh. Unix doesn't let you send signals to processes you don't own. Would you want other people to be able to kill your running processes? You could use 'su', but then you need to supply a password, which you cannot supply from the command line. Consider installing 'sudo', which you could configure such that you don't need to give a password to be able to issue the kill command as root (or as another users). But that would kind of defeat the purpose of having different users, doesn't it? It's certainly a security concern. Abigail	[reply]

`my $pid=shift; system("sudo kill $pid");` [download] BUT, Caution: DON'T TRY THIS AT HOME :-) Bottomline: If the OS won't let you, perl won't either Updated after CB with diotalevi --------------------------- Dr. Mark Ceulemans Senior Consultant IT Masters, Belgium	[reply] [d/l]

If anyone is curious the original post was a joke on `sudo rm -rf`. I considered the node because it was reckless. It wouldn't have worked anyway but that wasn't the real problem. `__SIG__ use B; printf "You are here %08x\n", unpack "L!", unpack "P4", pack "L!", B::svref_2object(sub{})->OUTSIDE;` [download]	[reply] [d/l]
