The stupid LRU system man was not meant to know.
cthlru <cache name> - Present a series of cached values with the least
recently used at the end.
cthlru <cache name> <value> - hit a value. It will be added to the cache or
have its time warmed.
cthlru sets you up with a Least Recently Used cache that you can use in programs such as dmenu to generate a list of options ordered by recent use.
I was drinking tea and thought it'd be a horrib cool thing.
At first I did something kind of stupid with sha1sum and ls -ut it made me
really uncomfortable and I didn't know why. On the bus home I realized I should
just have a history file that has only unique items.
