Wait… YOU CAN DO THAT?!
sudo !!
<Esc> k I sudo <Space> <Enter>lol no vi mode

I used to have an alias ‘please’ for that.
Always amused me that
sudo !!is actually more keypresses (at least on keyboards where typing!requires holding Shift).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.If you have an actual home key. If it’s ctrl+a or (IIRC, AFK) ctrl+← then we’re even.
And if we track hand movements then pressing ! twice may be faster than moving to another key.
But yeah, it’s not at all clear that
sudo !!is faster like you’d expect it to be.
But it’s faster since your hand move less and you can keep
shiftpressedI use zsh with the sudo plugin. Double tap
escand your current or last command will be prefixed with sudo.I don’t dabble in black magic. /j
It’s actually pretty neat.
Ctrl A is easier to reach than the home key
Unless you’re in a default screen session (I always thought ^A was such a dumb default for screen to use).
Screen must have been written by someone who wasn’t familiar with the shell. It’s the only logical explanation.
Maybe someone who only used csh? I can’t remember if ^a is a default in that shell. I thought it started with ksh or bash.
ETA: just looked it up and I’m dumb. Comes from emacs (of course) and looks like it was introduced in bash. I guess I could claim ignorance, being a VI man, but I actually knew at some point that it came from emacs. I think I can count on 1 hand the number of times I’ve used emacs
You can also just do a
sudo !!the!!is a shorthand for whatever you tried to run previously.wish i could alias that
alias ffs=“sudo !!”
alias ffs='sudo $(history -p !!)'That doesn’t work? I would have thought it would work.
!! Gets replaced by whatever was run before the alias command
Was about to say, why would you copy anything when using
sudo !!lolNot all shells support that.
I use fish btw.
Holy shit I wish fish supported it. I just press up arrow then hold left arrow and manually type sudo. It fucking sucks
I’ve used it for so many years that it’s not an issue anymore. I remember using !! a lot but it was literally just for sudo. Now i either write what I need and do up or write what I need and then press alt+s, which seems even more intuitive now.
… are you not aware of Alt+S?!
Does your keyboard not have a home key?
I made my own !!
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
I don’t even know what I use anymore. My distro seems to keep changing it when I reinstall.
echo $SHELLLol, thanks. Now I know.
I learned something new today!
I completely forgot about this one!
oh my zsh plugin just let’s you press esc twice :3
alias fuck="sudo !!"Wait, you don’t have The Fuck installed?
Waiting for it to be rewritten in rust
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.
The manual is a good place to start. It’s just GNU Readline under the hood.
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.
Or press Ctrl-S and take a nice walk outside
Cannot find any reference online. What is this supposed to do? Not at a PC right now.
!! 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.
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.
Seem to be a
fishshell thing.I tested on my good ole trusty
bashand got nothing so I went searching.EDIT: Clarification :
alt+sseems to be afishshell thing.Ya I haven’t tried alt s. Never heard of it before either.
But if you typed in sudo !! Right after, then you’re really fucked.
Not if you don’t type your password.
Adding to this, if you notice numbers next to your previous commands when you run history, you can do !<number> and it will rerun that command. Probably the second cool shell trick I learned back in the olden days or yore (mid-90s?) after ⬆️
ctrl-r is generally quicker
Learned that one embarrassingly much later.
I assume if you are silly enough to type in rm -rf /etc, then you are silly enough to type in your password 😅
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.
If you hit ctrl-s, ctrl-q will unfreeze
Interesting, why is that? Like what feature is that?
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…
THAT’S WHAT IT’S FOR??
Now that I think about it, it does seem pretty obvious.
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.
It’s part of the terminal emulator flow control
x👏off👏… x👏on👏… x👏off👏, x👏on👏…flowcontrol.
Ctrl + S freezes your shell yes. But Alt + S?
Ah indeed, ALT+S does nothing. I must have pressed both before realizing it was frozen.
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)
