I've used wget and path variables before not knowing what it does thinking it's some hardcore deep into the linux vortex stuff that needs me to be one with the abyss to understand. Adding new users with CLI was pretty cool. Still kinda confused about the exact differences between sudo and root user. Using find and -exec was pretty cool, so was using grep with -P by piping things from history.

There were many other stuff like sort, lspu, lsof, htop, ps, ps aux, cut, so on and so forth. By doing this it made me much more comfortable doing terminal stuff.
