grep faster and more effectively than grep, using grep
Authored by: sweth on May 25, '07 06:04:19PM

You need to learn to read better (which might explain why manpages are so baffling to you). I never said that the hint wasn't fast enough; I said that it was pointless, because the speed of an interactive invocation of grep is very rarely going to be functionally helped by the switch to fgrep, and if speed really were an issue, using fgrep would rarely be the best solution. I've seen literally hundreds of people over the years get caught up in trying to optimize things that don't need to be optimized, and in ways that don't really help them; all I was trying to do was prevent people from wasting their time on what is almost always a fruitless endeavor.

(I'll concede that for people not familiar with regular expressions, the ability to use fixed strings instead of regexes could make fgrep useful, but that's not what the hint claims to be showing people to do. And judging from the current rating of the hint, it would seem that I'm not alone in not thinking that this is not a great hint.)
