Mint comes with dir aliased for ls, and the only other one I regularly use is cls for clear.

Yes I grew up on DOS, how can you tell?

People type clear instead of CTRL+l?

I’ve never had a terminal that that didn’t work in. Or at the very least have a shortcut be able to be set for.

I often use clear when I need to rerun the same command and want to see the output in isolation each time, so I might run clear && ./build.sh and then just press the up arrow and run it again.

But I think, many people are also just not aware of the keyboard shortcut or don’t care to remember it, since they don’t use it often and clear is easy enough to guess.
