Re^2: Golf: reverse sort /etc/passwd by UIDby Tommy (Chaplain)

Technically it's *possible* that usernames can be completely numeric, but that's outright abusive--borderline illegal, and definitely prone to all kinds of problems.
If I we were dealing with "abusive" uid's, it wouldn't be too hard to add a neg look-behind assertion.
Now, for the meat and potatoes... I did run into some small typos in your code, but after correcting them, it worked. *slow and dramatic golf clap*. I had a hunch it could be done with regexes!! I've said it before, and I'll say it again... you have a dark gift my friend (sarcasm).
Read through the rest of the thread for the reason why this awesome snippet didn't quite work as intended...
A mistake can be valuable or costly, depending on how faithfully you pursue correction
