It's a "useless use of head". He/she should have gone:

`grep -m1 arathorn users`

Instead of:

`grep arathorn users.txt | head -1`

Commenters these days.

I still dont get that logic. What if it turns out i want to stick a prerprocessing step before grep? With a "useless" use of cat, thats easy. Without it, i need to do some rearranging. Not convinced.
