Linux Command Cheat Sheet

I just stumbled across this while trying to learn a bit more about using the command line, and thought others might appreciate it. It comes in a printable format so you can stick it up on your wall :)

On a related note, the website cheat.sh is also a great resource. Just curl it with the command you want to learn about as the endpoint.

For example, if I want to learn about grep, just open a terminal and

$ curl cheat.sh/grep

And a short and sweet description with examples will be returned.

At that point just use 'man grep'.

curl cheat.sh/command is more useful because it just spits out common examples. man is only useful if you need complete documentation or need to build a complex oneliner.

I never remember hot to extract tar files. Would you dive into the documentation for that or look up a cheatsheet?

Cheat.sh has usage examples, with short descriptions. It’s purpose is remembering something you have already done. It’s much more similar to --help flag than full manpage.

Reading the cheat.sh of a command I don’t know at all is rarely useful. I use it when simply listing the flags isn’t enough, or the output unhelpfully long. curl returns so fast that it’s faster to request data from external server than read through three paragraphs.

If you haven’t tried it, give it a go. The whole point is to be very quick to type and give back text that is fast to read.

My main issue with this is it requires a cheat sheet just to view a cheat sheet.

I added a custom function to my bashrc:

cheat-sheet() {
	curl cheat.sh/"$1"
}

Then you can call cheat-sheet grep for example

On a whole different level... (on enthusiast lvl hardware) a Llama2 70B running with 4 bit GGML on a 16GBV 3080Ti 12th gen Intel with 64GB can do bash and Python completely offline at a cheat sheet/stack overflow level without major errors. I just spent a day modifying someone else's python script and never went online for anything, have never been good at Python, and haven't messed with it for years. I actually got more done than I ever have before in a single day mostly because I didn't need to search documentation. FOSS/almost FOSS/offline AI rocks.

Ublock origin works too
