That's a good point; I wasn't aware of sort's --parallel option. Though I also note that "sort --parallel=4" limits the number of threads to 4, rather than increasing the number of threads from 1 to 4, so the comparison isn't exact. > sort doesn't > have a matching short option though, so I went with -M to suggest > "mulithreaded" (since, as you point out, -P is already in use).

I'm a little unhappy about the idea of proliferating the world's set of short options in this space, to be honest. If grep didn't already have -P, I'd be happy enough with -P and either --parallel or --max-procs, but I'm not terribly fond of the idea of introducing either -M or -p. -- Aaron Crane ** http://aaroncrane.co.uk/
