Ctrl+R

https://www.commitstrip.com/en/2017/02/28/definitely-not-lazy/

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!

Ctrl r

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

Pretty much, yeah.

Rather than jot down in a text file the various ffmpeg commands I use frequently...

Raktajino@laptop:~/Downloads$ history | grep ffmpeg

More like ⬆️⬆️⬆️⬆️⬆️⬆️ mother fucker ⬇️

I just mapped page-up to search (and you can too)

history | grep ‘part of the command I remember’

history | grep [the thing]

Fuck that hits so hard.

history | grep then !cmd_number

history | grep thethingyou'relookingfor

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.

!ssh

run the last command that started with ssh

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.

just use atuin.

^R

fzf is a nice tool for this and other things

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)

Or just use fish shell. Rarely need ctrl+r anymore.

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).
