In short, it signals processes by name, so you don't need to know the PID. You can use system() to run it from Perl, like this: #!/usr/bin/perl use warnings; use strict; system 'killall -KILL pppd'; sherm--

That definitely looks like a step in the right direction. Now the only problem is that 'pppd' a process owned by root. Should my script be run as 'root'? That sounds kind of dangerous! ... can it / should it be done? When at the Terminal I have to 'sudo kill' and the get asked my password. How would I do a 2 step process from 1 perl script?

From the sudo manpage: -S The -S (stdin) option causes sudo to read the password from stan- dard input instead of the terminal device.

Long shot but worth a try...
This is not a problem/question with/about perl, but one that I think can be solved *with* perl in macosx. Please forgive it's off-topicness: Internet Connection in Panther 10.3.2 sometimes hangs forever in its Disconnecting... status. I have not been able to find a reason nor a cure: I've found people who also have this problem but the circumstances, causes and systems all seem inconsistent. Restarting is the only solution for GUI-only users (login out and back in won't do it). I've been using the Terminal to find the process id whose name is 'pppd' via top and then sudo-killing it (for some reason you have to kill it twice before it finally dies [EMAIL PROTECTED]*!). I though I'd write a perl script to do the process described above and share it with the affected users community and feel good about it for a couple of days. I've using perl for 5 years in self-contained programs that have minimal interaction with the machine they run on, so it is only until now that I come to realize my profound ignorance in this field: I was not even able to take the first step : getting the process's id! I cannot find any function resembling 'getpidbyname'. Can somebody point me in the right direction and / or contribute an idea for this?
