I recently learned to use a for loop on the command line to organize hundreds of files in a few seconds.

ll

df -h

du -sch

Ctrl+r

diff -y -W 200 file1 file2

Shows a side by side diff of 2 files with enough column width to see most of what I need usually.

I have actually aliased this command as diffy

ctrl-r

searching bash history

du -sh * | sort -h

shows size of all files and dirs in the current dir and sorts them in ascending order so you can easily see the largest files or dirt ant the end of the list

ls -ltr

Shows the most recently modified files at the end of the listing.

Btop is an amazing resource monitor

Not a command but bang expansions. For example !? is the args of last command useful for stuff like mkdir foo ; cd !?

https://www.redhat.com/sysadmin/bash-bang-commands learn these. you suck at using your computer if you don't know them.

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.

nmtui. But that's because my router is trash.

ncdu

jq

Seems like an appropriate place to share https://github.com/agarrharr/awesome-cli-apps

I'm a fan of ripgrep and lsd in particular.

ls -al

Neofetch

For Debian based/descended distros:

sudo apt-get update && sudo apt-get upgrade

And technically I also regularly use

redshift -O 3000

all of the blue light filter programs try to align themselves with a user's geographic location and time, but I don't keep normal hours

touch 😏

I use atuin (link) all the 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 }

g-push which is alias for

git push origin `git branch --show`

Which I'm writing on my phone without testing or looking

nano

I've recently started using tmux when starting a new SSH session to try to build the habit.

du -sh /too/bar to get size of files/folders. sudo !! inserts sudo into previous command when forgotten. yay for full system update if yay is installed. cat reads files.
