too bad that cunt released it under a non-free license so you'd have to use the whole slow, shitty program instead of taking out and using just the useful parts. also it's a lot slower than building an index and then seeking to a random position in the index like >>34 described.

also, >>40. you'd have to install it pretty much anywhere you want to use it.

Have you heard of fortune? It comes with a neat little utility called strfile that reads a file and dumps out a cache of line positions and stuff that's useful for pulling out random lines.

If you have some spare time, I suggest browsing through the source to the program. It's got a handful of nifty gems of code for various kinds of text-mashing that have come in handy at unexpected times.
