On my Terminal that just makes it so I can't type anymore, I feel like I'm doing something wrong...

My solution to the problem is CTRL+U, type sudo, CTRL+Y.

Need to use the fish shell instead of the others for this to work. (May be a way to enable it in other shells but I'm not sure how)

If you hit ctrl-s, ctrl-q will unfreeze

Top text should maybe say copying by, rather than copying then? Since sudo !! will automatically copy the previous command with sudo in front of it, so there's no manual copying involved

Yeah I remembered that after uploading the meme.

Ctrl + S freezes your shell yes. But Alt + S?

You can also just do a sudo !! the !! is a shorthand for whatever you tried to run previously.

I completely forgot about this one!

x👏off👏...
x👏on👏...
x👏off👏, x👏on👏...flowcontrol.

Not all shells support that.

I use fish btw.

Was about to say, why would you copy anything when using sudo !! lol

Cannot find any reference online. What is this supposed to do? Not at a PC right now.

alias fuck="sudo !!"

Ah indeed, ALT+S does nothing. I must have pressed both before realizing it was frozen.

Interesting, why is that? Like what feature is that?

Is this a shell thing or a terminal thing? It doesn't work for me on foot.

!! Just puts in your last typed command. So if you typed rm -rf /etc, you wouldn't have permission. But if you typed in sudo !! Right after, then you're really fucked.

Not sure, I assumed universal because you use it with your history. Type history, see the number next to the command, do a !nnn and it will run that command from history

Ah I wasn't clear -- those, I knew. It's alt+S I don't know. I'm at my machine now and it doesn't seem to do anything on Pop_OS.

I made my own !!

Or press Ctrl-S and take a nice walk outside

I don't even know what I use anymore. My distro seems to keep changing it when I reinstall.

Oh, !! definitely works. I meant Alt+S shortcut.

I know what you meant (I have one for fish as well), but I chucked because you looked very enthusiastic about it!

The fish function for !! is super useful though

It's part of the terminal emulator flow control

I learned something new today!

Short answer, terminals are built on the same technology as physical terminals from the 60s and 70s when controlling the flow of data from the server was a more useful feature.

I know alt +. inserts the last argument of previous commands. There must be a good list of alt commands somewhere because they're pretty damn useful.

Ya I haven't tried alt s. Never heard of it before either.

Oh, LOL

Same reason there's a ScrollLock key on keyboards. Didn't always have scrollbars and if the application prints more than you can read, you want to pause that...

echo $SHELL

@Dionysus@leminal.space found out that it's a feature in fish shell, which I can confirm.

Always amused me that sudo !! is actually more keypresses (at least on keyboards where typing ! requires holding Shift).

Ctrl A is easier to reach than the home key

I use zsh with the sudo plugin. Double tap esc and your current or last command will be prefixed with sudo.

You just blew my mind. sudo [space] [shift] !! [enter] (4+1+1+1+1+1) is one keypress longer than ↑ + home + sudo + space + enter (1+1+4+1+1). In your face, universe.

Wait, you don't have The Fuck installed?

I don't dabble in black magic. /j

It's actually pretty neat.

Thanks. I think I should check out fish soon, I keep seeing it a lot lately and it seems to be made for lazy people like me. :)

Seem to be a fish shell thing.

I tested on my good ole trusty bash and got nothing so I went searching.

EDIT: Clarification : alt+s seems to be a fish shell thing.

But it's faster since your hand move less and you can keep shift pressed

But if you typed in sudo !! Right after, then you're really fucked.

Not if you don't type your password.

THAT'S WHAT IT'S FOR??

Now that I think about it, it does seem pretty obvious.

I assume if you are silly enough to type in rm -rf /etc, then you are silly enough to type in your password 😅

Unless you’re in a default screen session (I always thought ^A was such a dumb default for screen to use).

Adding to this, if you notice numbers next to your previous commands when you run history, you can do ! and it will rerun that command. Probably the second cool shell trick I learned back in the olden days or yore (mid-90s?) after ⬆️

The manual is a good place to start. It's just GNU Readline under the hood.

Lol, thanks. Now I know.
