Without more details, you may need to kill the parent process. Often, when you fork off a process, the $pid return is actually the bash shell (usually :-) ) , and your actual program is spawned from that. It can get tricky to know exactly which pid you are talking about. See "perldoc Proc::Killfam"..... and here is a manual way.

You need to give more info on how you are creating the process, so we can tell if a shell gets involved, and you thus have a parent process. 

#!/usr/bin/perl
use warnings;
use strict;

#robau
#This subroutine takes two arguments, the parent process ID 
#and the numeric signal to pass to the processes 
#(which would be 9 if you wanted to issue a -TERM). 
#Using Proc::Process you could find the process ID 
#of the process login -- zentara with something similar 
#to the following :

#my $proc = Proc::ProcessTable->new;
#my @ps = map { $_->pid if ($_->cmndline =~ /login -- zentara/) } @{$p
+roc->table};
#&killchd($_, 9) foreach @ps;

&killchd(9895, 9);
#kill -9  process 9895

sub killchd ($;$) {
use Proc::ProcessTable;
my $sig = ($_[1] =~ /^\-?\d+$/) ? $_[1] : 0;
my $proc = Proc::ProcessTable->new;
my %fields = map { $_ => 1 } $proc->fields;
return undef unless exists $fields{'ppid'};
foreach (@{$proc->table}) {
kill $sig, $_->pid if ($_->ppid == $_[0]);
};
kill $sig, $_[0];
};
