I’ve used Linux full-time since late 2020 and I never knew about ctrl+y and ctrl+u.
I’d also like to contribute some knowledge.
aliases
You can put these into your ~/.bashrc or ~/.zshrc or whatever shell you use.

tab completion works in more places than you might expect
I’ve found tab to be such a nice “please give me a hint” button.
Bonus tip : Sometimes you won’t get auto complete because there’s too many possibilities and the computer can’t be certain which one you want. Hitting tab multiple times will show the possibilities, so you can type in enough characters to remove ambiguity, hit tab again, and boom auto complete!
…That was a terribly convoluted explanation I’m sorry. Just try hitting tab multiple times for fun if you’re stuck it’s kinda handy. Lol
If you’re looking for a full list of these kind of navigation shortcuts, they all come from readline so read the man page for that. Or just look up the basic navigation of emacs which is what readline is mimicking.
A neat thing is that a lot of command line programs use readline. So learning and configuring it will also be useful in for example the Python REPL and calc.
Here are some neat configuration options you can put in ~/.inputrc
set completion-ignore-case on
set show-all-if-ambiguous on
set completion-prefix-display-length 9
set blink-matching-paren on
set mark-symlinked-directories on
And if you are a sensible person who is used to vim
Explains why they are so illogical! Unfortunately i think its better to just learn the defaults since i remote into lots of servers where i dont carry my config
That’s good to know. It’s interesting that the other commenter thinks emacs shortcuts are illogical. I’ll make my best guesses at the logic
ctrl-a/ctrl-e for start/end of line
a is the beginning of the alphabet; e for end (of line)
ctrl-u to clear the command you’ve typed so far but store it into a temporary pastebuffer
ctrl-y to paste the ctrl-u’d command
No idea here. Seems similar to nano with k-“cut” and u-”uncut”.
ctrl-w to delete by word
w for word obviously.
ctrl-r to search your command history
alt-b/alt-f to move cursor back/forwards by word
r reverse, b back, f forward. Not sure why alt vs control though; presumably ctrl+b and ctrl+f do different things although I know emacs likes to use Alt (“Meta”) a lot.
In the 1980s, Digital Equipment Corporation had a word processor, WPS. Ctrl-u cleared the line you were typing and put it into the paste buffer. Maybe legacy usage?
alt-. also pastes the last argument of the previous command (useful if you need to modify it a bit)
instead of any shortcuts starting with “alt” you can also press “esc” followed by the second key, e.g. pressing “esc”, releasing it and then “a” is the same as pressing “alt-a” (useful if you have only one hand available, or if alt is not availalble)
if you put a space before a command, it will not be saved in history (useful sometimes, e.g. if you pass a password directly as an argument)
sudo !!which footells you where thefooprogram is locatedls -lacdwithout any args takes you to your home dircd -takes you to your previous dirWhat’s the shortcut for scrolling the terminal?
Saved! Thank you so much.

zellij - tmux but easy and with nice colors
atuin - shell history but good, fuzzy-searchable. If you still have the basic shell history (when pressing
ctrl+r), I cannot recommend this enough.ranger - a terminal file-browser (does everything I need and way more)

I’ve been using the commandline for so long but was always too lazy to look up the rest of these commands after ctrl+a/e and ctrl+r THANK YOU!!!
post this commend again and again! There’s always lazy idiots like me who will be helped that way!
Nice list, TIL about
