pv (Pipe Viewer) is a command line tool to view verbose information about data streamed/piped through it. The data can be of any source like files, block devices, network streams etc. It shows the amount of data passed through, time running, progress bar, percentage and the estimated completion time.

Getting cheatsheets via curl cheat.sh/INSERT_COMMAND_HERE

No install necessary, Also, you can quickly search within the cheatsheets via ~. For example if you copy curl cheat.sh/ls~find will show all the examples of ls that use find. If you remove ~find, then it shows all examples of ls.

I have a function in my bash alias for it (also piped into more for readability):

function cht() { curl cheat.sh/"$1"?style=igor|more }

less, watch

ls

jq

sudo !! to rerun last command as sudo.

history can be paired with !5 to run the fifth command listed in history.

compgen -back to see all valid things you can type into a shell.

Not a specific command, but I learned recently you can just dump any executable script into ~/bin and run it from the terminal.

I suffer greatly from analysis paralysis, I have a very hard time making decisions especially if there's many options. So I wrote a script that reads a text file full of tasks and just picks one. It took me like ten minutes to write and now I spend far more time doing stuff instead of doing nothing and feeling badly that I can't decide what to do.

Ctrl-r with https://github.com/atuinsh/atuin is amazing. Never forget a command you used ever again.

sudo pacman -Syu

not sure if it counts as a command, but i use the up arrow to scroll through previous commands like, almost every time I open a terminal.

locate, from the mlocate package. So useful. Honorable mention goes out to tldr.

clear. Constantly, and for no reason.

shred -vzf

history | fzf

Not a command as much as I press the up arrow a lot. I'm.pretty lazy and hitting the up arrow 12 times is easier then retyping a complex rsync command.
