sudo !! really can’t be beat. It’ll run your last command as sudo. Also love a good ls -la (lists what’s in your current directory plus information about each item).

| grep [search-item] It helps to be able to easily filter stuff out of the results of another command.

Not a command but “command substitution”. $() comes in handy a lot especially for one liners

My favorite bash command is `fish`. It takes you to a decent shell

AKA "Ctrl+shift+r" This is a reverse history search, and it's BALLER!!! No, srsly, it's a fucking life safer, it will literally save you more than a day of your life if you use Linux a lot.

xargs, honestly. Being able to pipe data and use xargs in super creative ways is my favorite!

A real favorite bash tip: functions can be like this: foo() { ... } but leaks variables and `cd` changes etc. unless you're super careful. You can tighten this up by using a subshell: foo() ( ... ) and now nothing inside the function leaks out.
