'How do I enable "!!" in fish?

I often used $ sudo !! while using bash. After switching to fish, I noticed this no longer works. Due to search engines not supporting search for special characters, this has been particularly difficult to figure out on my own. I presume I just need to add/change one line in the config, but I don't know what that would be.

Oldish question, but I'm surprised that there's been no mention of fish shell's "pre-pend sudo" keybinding Alt+s.

With the default, out-of-the-box keybindings, sudo !! can be accomplished with either:

  • Alt+. followed by Alt+s
  • or ? followed by Alt+s, but that does move your finger a bit far from the "home row" for those that care (and I do).

The first key-chord repeats the previous command, then Alt+s prepends sudo to it.

Edit: With fish 3.2 and later, one of my favorite new features is that you don't even need to retrieve the previous line via Alt+.. Just Alt+s with no other text typed at the prompt will result in the prompt being automatically populated with sudo + the last command typed.

There are some ways of implementing this using shell hacks listed at https://github.com/fish-shell/fish-shell/wiki/Bash-Style-Command-Substitution-and-Chaining-(!!-!%24-&&-%7C%7C)

For example:

function bind_bang
  switch (commandline -t)
  case "!"
    commandline -t $history[1]; commandline -f repaint
  case "*"
    commandline -i !
  end
end

function bind_dollar
  switch (commandline -t)
  case "!"
    commandline -t ""
    commandline -f history-token-search-backward
  case "*"
    commandline -i '$'
  end
end

function fish_user_key_bindings
  bind ! bind_bang
  bind '$' bind_dollar
end

funcsave bind_bang bind_dollar fish_user_key_bindings

The easiest way is to install the Fisher package manager; and then install the package !!, e.g.:

$ fisher install oh-my-fish/plugin-bang-bang

p.s.

Not only do you get back the use of !! (last command used) but also !$ (last command arguments.)

You could also use the plugin through the older installer omf.

Why reinvent the wheel when you have an easy to use a package manager like Fisher.
