Some suggestions:
Don't use "system" use back-ticks ``. Like this: my $outr = `ps -ef|grep Jones|grep -v awk|grep -v ksh`;
That will assign the output of your ps to $outr.

Or: 

my $outr = `ps -ef|grep Jones`;
@outr = split(/\n/, $outr);
foreach (@outr)
{
   unless (($_ eq /bin/ksh) or ($_ eq awk))
   {
      print "$_\n";
   }
}

I think that one of these will do what you want. And if
you don't want to use ps -ef there are some modules that
will return this kind of system process info also.
