sudo fish
Over the last week I setup a Linux VM alongside my current work—I needed decent docker support and also I got somewhat fed up with Windows as a development system.
Setting up a new system means I got to use sudo
a lot, but often I typed a command line and only then realized I had to use sudo
.
So I added a new editor binding to my ~/.config/fish/functions/fish_user_key_bindings.fish
:
function fish_user_key_bindings
fish_default_key_bindings
# Prepend sudo to the command line with M-s
bind \es sudo-commandline
end
~/.config/fish/functions/sudo-commandline.fish
looks like this:
function sudo-commandline -d "Insert sudo at the beginning of the command line"
set -l cmdline (commandline)
commandline -r -- "sudo $cmdline"
end
Now I can just type Alt-S
in Fish shell and I get sudo
prepended to my current input.
A small thing, but it already saved me a lot of frustration!
