Hi
I'm fairly new to Perl and am struggling with what is probably a simple solution to a problem.
I'm using Proc::ProcessTable to get a list of all currently running pids on a system.
I need to traverse this array to ascertain whether a certain pid is present or not. 
$process = new Proc::ProcessTable;
@fpid = "1234";

To get access to the pid I would use $process->pid. The question is what is the best way to see whether this pid is present or not ? Should I use a grep or exists or some other method ?. My knowledge of Perl is at the novice stage hence my question.
