Wrong. It's been this way in coreutils as long as I can remember; are you not on a Gentoo Linux system? man -K works exactly as the example in the doc shows. Here's the output of man man: -k Equivalent to apropos. -K Search for the specified string in *all* man pages. Warning: this is probably very slow! It helps to specify a section. (Just to give a rough idea, on my machine this takes about a minute per 500 man pages.) . . . -K is a perfectly valid option. Something is broken on your end.
Damn... sorry much for any inconvenience Josh.
