FYI, in bash, "sudo !!" re-runs the previous command with sudo.

[papln → nfriedly]

That's not "funny" enough, unless the "!!" is replaced by an emoji.

[anoncake → papln]

    papln used multiple exclamation marks and is clearly insane. This incident will be reported.

[toyg → papln]

alias goddammit=sudo !!

[blacksmith_tb → nfriedly]

I use it all the time! But also worth remembering that !$ is the object of your last command, so you could do something like

cp /some/tortured/path/to/file.txt /some/other/path/file.txt

chown myuser:myuser !$

[gitgud → nfriedly]

Thanks for that little tip! It's a constant mistype for me...

    $ apt install something
    E: Unable to acquire the dpkg frontend lock 
      (/var/lib/dpkg/lock-frontend), are you root?

up arrow

ctrl-a (readline command for beginning of line)

type "sudo"

Also, ctrl-w is really useful. Heck, learning the readline editing keyboard in general is really useful.

[al_form2000 → hackbinary]

        $ foo bar baz<cr>
        ^P^A<esc>u
        $ FOO bar baz<cr>

That's three keystrokes less - even for the history (!!) version. :-)

[apexalpha → hackbinary]

sudo !!

[rudiv]

Remember, all caps when you spell the man name.

[timeattack]

Most often case is when you forget to type sudo before command. This implementation propose to re-type executable name in all-caps (or type it in all-caps beforehand).

More efficient approach is to use keybinding like Ctrl+T to prepend sudo to the current command (or to the previous command if current is empty).

[al_form2000 → timeattack]

As mentioned above, you don't need to retype:

        $ foo bar baz<cr>
        ^P^A<esc>u
        $ FOO bar baz<cr>

As for ^T, I'd wholly forgotten about bind, inputrc and all that- but of course both your proposal and the above can be put into an inputrc macro and bound to a key. However the all caps version is shorter when you remember you need sudo in the first place ;).

[faeyanpiraat → timeattack]

or use "sudo !!"

[sonofgod]

This is hideous. Congratulations! :D

[gnulinux]

Isn't typing 'sudo yum' faster than 'YUM'?

[brirec → gnulinux]

…is that a sarcastic question? How would typing 'YUM' NOT be faster than 'sudo yum'?

I can't deny that something feels terribly wrong about this sort of script, though.

[gnulinux → brirec]

because you need press shift while pressing y, u, m to type YUM. I definitely type sudo yum faster.

[bradknowles → gnulinux]

Do you not have a CAPSLOCK key?

[anoncake → bradknowles]

Many people map capslock to Ctrl or Escape. Or both, depending on whether the key is held or tappped.

[teamspirit → bradknowles]

My caps lock is mapped to ESC.

[taejo]

Did some kind of automoderation break the title by changing ALL_CAPS to All_caps?

[al_form2000 → taejo]

I remember writing the title as

    ALL_CAPS => sudo all_caps

So it appears something did actually change it.

[weinzierl → al_form2000]

Titles are automatically titlecased when submitted but not when edited. The workaround is to submit and immediately edit afterwards.

Unfortunately many blogs have their titles all uppercase instead of using small caps. For me the use case where I copy an all uppercase title and want it to be titlecased on HN is much more common than the case where I actually want a string of caps. I'm quite ok with the current behavior.

[dang → al_form2000]

weinzierl got it right. We've edited the title back.
