Nice tricks! I like the temp ram disk idea. Im going to be using that one a lot I think,

Nice tricks indeed! I had completely forgotten about using "!!" to repeat the last command. I'm not sure how useful using "fc" is to edit the last command, though. I mean, if you're going to edit the command, it seems just as easy to press the UP key and edit it right there anyway - the forward and back keys work to move through the command while leaving the other chars in place.

... if you're going to edit the command, it seems just as easy to press the UP key and edit it right there anyway...

Yeah... but sometimes a proper editor's power can be useful. I often type long commands, usually starting smallish and getting large, and getting around them with the arrow keys can be slow.

(!! and the similar !$ are ancient tricks from the C shell, I guess from about 1980. !! is short for !-1, and !-2 (the second before this), !-20, (the twentieth), !bob (the last starting with bob) and so on. I have the command number in the prompt, and "r" aliased to "fc -s", so "r 44" repeats number 44 in the history immediately, and !44 lets me adjust it first.)

That's a very good point!

I seriously need to try that.. sounds quite useful.

That and the "!!" trick as well.

I've been using Linux since 1998 and half of those CLI commands I was not familiar with. *facepalm*

I've bookmarked his channel and have watched a couple others as well. That guy is very sharp!

So is pythonprogrammer, a PhD Physicist who uses Anaconda & Python to do a lot of his data analysis. He pushes "data science" a lot.

That's what I've been doing, and using the grep command to pipe specific search results: "history | grep someword"

My 79 year old brain can't remember ever learning !! or fc or half of his other tricks.

That's a good point. The command line has accumulated so many tricks over so many decades one has to be choosy about which tools one keeps in the toolbox to hand. I've set up shell functions that have recorded every command I've typed, timestamped, for the last several years in a history directory and often I just run grep in that directory.

That's exactly what I've been doing for years!

We're obviously creatures of habit!
