Alternative to Onyx


I'm looking for an alternative to Onyx. A few months ago, I stumbled onto an alternative. It contain a library of Unix or Terminal commands with an explanation for each. I can't seem to find this thing again. If anyone could suggest to me some alternative, it may be the one I'm looking for.
I like OnyX
YASU is very simple to use
I also use Maintain

I have never looked at Clix, and I thank you for giving me a link to that. I think I will be referring to that for some of the work that I do.
