  • Quick tip for the author and those reading, instead of doing as in the article noted e.g. sudo nano or the like, you can use sudoedit (or sudo -e). The advantage of this is that it will use whatever you have configured as an editor (through $SUDO_EDITOR, $VISUAL or $EDITOR), and will use your configuration files while editing instead of root’s, meaning if you have a sick custom neovim or emacs setup you don’t have to keep those settings files in sync with the root account. ;)





  • 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).
