You have:
my $searchfor = $#ARGV ? join(' ',@ARGV) : die("I need a process to lo +ok for.");
  • If there are no arg, $#ARGV is -1, $#ARGV is true, $search_for = join(' ', ()).
  • If there is one arg, $#ARGV is 0, $#ARGV is false, die("I need a process to look for.").
  • If there is two arg, $#ARGV is 1, $#ARGV is true, $search_for = join(' ', $ARGV[0], $ARGV[1]).
  • ...

You want

my $searchfor = $#ARGV >= 0 ? join(' ',@ARGV) : die("I need a process +to look for.");

Or better yet:

my $searchfor = @ARGV ? join(' ',@ARGV) : die("I need a process to loo +k for.");

I don't understand why that's one one line. It doesn't save anything. I just adds complexity.

@ARGV or die("I need a process to look for."); my $searchfor = join(' ',@ARGV);
