sudo

Easily prefix your current or previous commands with sudo by pressing <kbd>esc</kbd> twice.

Usage

Current typed commands

Say you have typed a long command and forgot to add sudo in front:

$ apt-get install build-essential

By pressing the <kbd>esc</kbd> key twice, you will have the same command with sudo prefixed without typing:

$ sudo apt-get install build-essential

The same happens for editing files with your default editor (defined in $SUDO_EDITOR, $VISUAL or $EDITOR, in that order):

If the editor defined were vim:

$ vim /etc/hosts

By pressing the <kbd>esc</kbd> key twice, you will have the same command with sudo -e instead of the editor, that would open that editor with root privileges:

$ sudo -e /etc/hosts

Previous executed commands

Say you want to delete a system file and denied:

$ rm some-system-file.txt
-su: some-system-file.txt: Permission denied
$

By pressing the <kbd>esc</kbd> key twice, you will have the same command with sudo prefixed without typing:

$ rm some-system-file.txt
-su: some-system-file.txt: Permission denied
$ sudo rm some-system-file.txt
Password:
$

The same happens for file editing, as told before.

Key binding

By default, the sudo plugin uses <kbd>Esc</kbd><kbd>Esc</kbd> as the trigger. If you want to change it, you can use the bindkey command to bind it to a different key:

bindkey -M emacs '<seq>' sudo-command-line
bindkey -M vicmd '<seq>' sudo-command-line
bindkey -M viins '<seq>' sudo-command-line

where <seq> is the sequence you want to use. You can find the keyboard sequence by running cat and pressing the keyboard combination you want to use.
