Ctrl+R
What the fuck!? How am I only learning this now, after years of linux as daily driver?!
Shit is usually a pain in the ass. The challenge is divining how much of a pain in the ass something has to be that someone else might have made a solution for it.
I didn't know you could ctrl+shift+c to copy in the terminal until a month ago when my linux n00b wife said "there has to be a better way to do this. I've been right clicking to copy for 10 years.
most DE's have a thing where you can paste highlighted text using the middle mouse button
Middle mouse button?!
Most mouse wheels can be clicked in place of the middle button, which has been removed from most modern computer mouses.
It's also known as mouse 3 if you need to find it on your mouse or want to bind it to something else.
It's also independent from the Clipboard so you can do it while keeping your clipboard

Congratulations! I remember where I was when I first learned it (in a noisy server room at the back of a machine shop).
Now pair it with FZF for fuzzy finding -- it's surprisingly easy to set up, just following any guide. It's insanely useful. I find myself even doing things like typing:
$ xinput --disable $(xinput --list | grep -i touchpad | grep 'id=[0-9]\+' -o | cut -d= -f2) # Disable synaptic touchpad trackpad pointer
commands with these like comments on the ends as sort of "tags" so I can ctrl+r search for them later. Yes, I know I could just use a named function, but this is like the step just before that--before I know if I'll be issuing the same command all the time, or just for the next couple weeks. (This one was from when I was resting my notebook on my laptop.)

I'm not going to say how long I used linux before learning this. It isn't "this many days old", but it may as well be.
I have 7 headless linux boxes running.

This but with FZF and ag
https://atuin.sh/ Does all that and a lot more, like showing if the command succeeded and which directory it was run in
Even quicker with zsh or atuin: write the first few letters then arrow up to cycle through all matches
Even quicker with fish: Write the first few letters then it auto-suggests the last-run command matching that prefix (and then you can still arrow up to cycle through all matches).
(There is also a zsh plugin for that, called zsh-autosuggestions.)

I used to be like this but people seriously. CTRL+R
Do it. Don't make this one of those things you've heard about and just never got around to trying. Open your terminal right now and CTRL+R and type any part of the command you did before. If the command you want is not showing first just hit CTRL+R again to go to the next one back.
DO IT.
Edit: I did learn from this thread today though that ZSH has it set to where you can just type part of what you're looking for then hit up to do the same thing. Neat!
You can empower Ctrl+r event more by using fzf. After I started using it, I can't imagine going back to without it.
Holy shit. I just tried it. ctrl+r is a revelation! How the fuck did I not know about this?
WHAT THE FUCJ IS THIS SORCERY BRO I'VE BEEN USING LINUX FOR AGES AND NEVER KNEW THIS BROOOOOOOOOO
Edit: I did learn from this thread today though that ZSH has it set to where you can just type part of what you’re looking for then hit up to do the same thing. Neat!
Fish too, it's fantastic.

What, and type 'ls' again?
Ctrl + R and start typing the command, it'll come up, press enter. Im just more lazy because I know there are still faster ways.
Edit: instead of hitting enter, keep pressing ctrl + R to cycle through history commands that contain what you typed in

history | grep ‘part of the command I remember’
Ha... That as if I would ever remember the part of the tool instead of the fact what it did 🤣
Also: Ctrl+r then type the part of the command you remember.

history | grep then !cmd_number
zsh-history-substring-search
I lazily type part of the thing I want like "sys" and then ctrl+⬆️/⬇️ and sudo systemctl start libvirtd etc. appear like magic.
You're in vim, you forgot to sudo, the file is read only and you have loads of changed you don't feel like saving off to /tmp and playing the copy file shell game.
[esc]:w !sudo tee %
it shoves the current buffer through tee (termina adapter) with sudo privs vim will warn you that the file changed, just [esc]:q! and don't let it save, you already saved it.

I see everyone posting about Ctrl+R, here's a couple more useful CLI shortcuts you might enjoy:
cd - (change directory to $OLDPWD usually the previous directory)
git checkout - (similarly checkout the previous branch)
Ctrl+A (return caret to beginning of command, great when you forgot a positional argument and you were almost done typing the command)
Ctrl+E (similar to Ctrl+A but move to the end of the command)

Everyone sharing their Ctrl+R tips, here's my Control+R question:
How does scope work? Some command history only seems to exist in certain tabs.
Also sometimes I Ctrl+R in a tab then the command is there but I forget I need a different one first, so I ctrl+c but the next time I search for that original command somehow it doesn't exist anymore.
I'm using the default terminal on Nobara (fedora based).
As far as I remember, there is a bash setting that controls whether the command history is written immediately after execution (in which case it is immediately available on all tabs/windows of the console) or after closing the session (in which case it will be available next time/potentially lost if the window is forcibly closed etc).
The default is the second one as far as I remember.
That said, I had changed to a more powerful one in zsh years ago, so it's been a while...

This actually doesn't depend on your terminal but on the shell running inside it. Bash is the default on most distros. I have also frequently had this issue. There might be config to fix it.
I switched to fish instead of bash, and now I use fzf and the https://github.com/PatrickF1/fzf.fish plugin and it works GREAT. There might be a similar thing for bash, I don't know.

Ah crap how did I set my battery charge interval again?
history | grep battery
history | grep bios
history | grep sudo smbios
Ah! There you are you little shit!
edit to add: Actually, I think the last time I did this I remembered some numbers I set it to before. So it worked well with something like "history | grep 75" even though there were a bunch of results.
