foreach my $pation (@occupation) { `ps -ef|grep -i $pation|grep -v grep|wc -l`; }
Why throw away the results of ps? (What's wrong with using backticks in a void context?)

If the intention is to count the number of instances of interesting programs from the process list, there is no need to repeat the execution of the ps command.

my @programs = qw(netman jobman mailman batchman writer); my @all_procs = `ps -ef`; my %counts; for (@programs) { $counts{$_} = scalar grep {/$_/i} @all_procs; } print "$_ $counts{$_}," for keys %counts; print "\n";
