Let's say I only want the 50 most common lines of a file:

Have I ever mentioned that 'sort | uniq -c' really ought to be folded into sort proper? (Not to get rid of 'uniq', but 'sort | uniq -c | sort -n' is far less efficient than a good tree algorithm... which is exactly why I wrote such a critter. When analyzing the output of 'strings' on a multi-GB core file, it makes a WORLD of difference...)
