> I keep on typing that in, but due to the nature of Fish, it can't (or won't) recognise it. But the excellent history functionality does make up for this a fair bit.

I was interested in this comment so I looked into the documentation to find out why this is. Here's a link to the FAQ for anyone else interested:

I'm a little sore that the FAQ Listed that as an alternative. That was how I did it in bash before I realized I could do "sudo !!" which was waaaaay more convenient.

It's a step backwards. Which I'm fine with, as long as you step forward again, in some way.

that works just as well I guess. But what if I want to make an alias for "sudo the last command"?

https://github.com/fish-shell/fish-shell/issues/288#issuecom... has some options.

Wonderful!

I made a slight variation (and also posted it there):

      function .runsudo --description 'Run current command line as root'
        set cursor_pos (echo (commandline -C) + 5 | bc)
        commandline -C 0
        commandline -i 'sudo '
        commandline -C "$cursor_pos"
      end
      bind \es ".runsudo"

Instead of outright `execute`ing the command, the above would save the cursor position. You can (theoretically) bind `\cs` so control-s adds the sudo (instead of option-s), but I couldn't get it to work.
