With the result is that they will keep doing it this way. Trust me on 
this one, I've seen it often enough. You tend to copy what you've seen 
somewhere, and not change it to something more efficient.

So he should have written it in a shell script. It's not that difficult 
to do a for-loop in the shell.

As a professional programmer, I shudder when I see these things. It's 
not just the waste of so or so many CPU cycles, but the fact that most 
people who do programming simply don't grasp the subject. It's like me 
repairing cars.
