    Upvote for “sudo !!” No one ever seems to know about “!!” And it’s such a useful command.

    I personally found out about it when I wrote a bash script that contained a password with two exclamation marks and I wondered why the last command kept being concatenated to the end of the password.

      My install of Endeavour doesn’t have it, and I haven’t been able to figure out what package to install to add it. Also haven’t tried very hard cause it’s just a minor convenience but if anyone knows …

      Oooh it’s cause I’m using fish isn’t it? Is there a way to add it?

        Had to check since this is something I’ve been wondering myself, but apparently not possible. From the fish FAQ:

        Because history substitution is an awkward interface that was invented before interactive line editing was even possible. Instead of adding this pseudo-syntax, fish opts for nice history searching and recall features. Switching requires a small change of habits: if you want to modify an old line/word, first recall it, then edit.

        However, for the use case here, with sudo:

        As a special case, most of the time history substitution is used as sudo !!. In that case just press Alt+S, and it will recall your last commandline with sudo prefixed (or toggle a sudo prefix on the current commandline if there is anything).
