A collection of modern/faster/saner alternatives to common unix commands. - ibraheemdev/modern-unix
I actually use/have used a couple of them. The tldr and glances are two that I've used quite a bit. I've tinkered with a few of the others but not really turned to them as regular tools. I am absolutely going to give 'cheat' a try, as I think it may be an excellent tool for newbies.
Either way, it's a pretty great list.
