    I used to have an alias 'please' for that.

    [–] cupcakezealot@piefed.blahaj.zone 1 points 56 minutes ago

    oh my zsh plugin just let's you press esc twice :3

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

    [–] akunohana@piefed.blahaj.zone 36 points 10 hours ago* (last edited 10 hours ago) (1 children)

    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.

    [–] logi@lemmy.world 3 points 1 hour ago

    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.

    [–] Axolotl_cpp@feddit.it 8 points 9 hours ago

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

    [–] Nilz@sopuli.xyz 9 points 10 hours ago (1 children)

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

    [–] akunohana@piefed.blahaj.zone 7 points 10 hours ago

    I don't dabble in black magic. /j

    It's actually pretty neat.

    [–] SkaveRat@discuss.tchncs.de 9 points 10 hours ago (1 children)

    Ctrl A is easier to reach than the home key

    [–] ClownStatue@piefed.social 1 points 3 hours ago

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

    [–] olafurp@lemmy.world 116 points 14 hours ago* (last edited 14 hours ago) (4 children)

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

    [–] juipeltje@lemmy.world 51 points 14 hours ago

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

    [–] Sarcasmo220@lemmy.ml 14 points 12 hours ago

    I learned something new today!

    [–] devfuuu@lemmy.world 19 points 14 hours ago (4 children)

    Not all shells support that.

    I use fish btw.

    [–] protogen420@lemmy.blahaj.zone 13 points 13 hours ago (1 children)
    [–] ArchAengelus@lemmy.dbzer0.com 11 points 12 hours ago

    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 completely forgot about this one!

    [–] Nilz@sopuli.xyz 24 points 10 hours ago

    Wait, you don't have The Fuck installed?

    [–] albbi@piefed.ca 9 points 11 hours ago (1 children)

    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.

    [–] softwarist@programming.dev 2 points 2 hours ago

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

    [–] imsufferableninja@sh.itjust.works 20 points 15 hours ago (1 children)

    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

    [–] Obnomus@lemmy.ml 7 points 15 hours ago

    Yeah I remembered that after uploading the meme.

    Or press Ctrl-S and take a nice walk outside

    [–] TrickDacy@lemmy.world 5 points 14 hours ago* (last edited 14 hours ago) (1 children)

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

    [–] cyberpunk007@lemmy.ca 6 points 13 hours ago (2 children)

    !! 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.

    [–] solxix@pawb.social 1 points 7 hours ago (2 children)

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

    Not if you don't type your password.

    [–] ClownStatue@piefed.social 2 points 3 hours ago

    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 ⬆️

    [–] cyberpunk007@lemmy.ca 2 points 5 hours ago

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

    [–] TrickDacy@lemmy.world 8 points 13 hours ago (2 children)

    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.

    [–] clif@lemmy.world 4 points 9 hours ago* (last edited 9 hours ago)

    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.

    [–] cyberpunk007@lemmy.ca 3 points 11 hours ago

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

    [–] eco_game@discuss.tchncs.de 8 points 15 hours ago (3 children)

    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.

    [–] imsufferableninja@sh.itjust.works 11 points 15 hours ago (2 children)

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

    [–] eco_game@discuss.tchncs.de 5 points 13 hours ago (3 children)

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

    [–] Ephera@lemmy.ml 7 points 11 hours ago* (last edited 10 hours ago) (1 children)

    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...

    [–] solxix@pawb.social 8 points 7 hours ago

    THAT'S WHAT IT'S FOR??

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

    [–] neclimdul@lemmy.world 4 points 11 hours ago

    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

    [–] qprimed@lemmy.ml 3 points 14 hours ago

    xπŸ‘offπŸ‘... xπŸ‘onπŸ‘... xπŸ‘offπŸ‘, xπŸ‘onπŸ‘...flowcontrol.

    [–] dracc@discuss.tchncs.de 8 points 14 hours ago (1 children)

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

    [–] eco_game@discuss.tchncs.de 5 points 13 hours ago

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

    [–] Dionysus@leminal.space 8 points 15 hours ago

    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)
