# sudo
|
|
|
|
Easily prefix your current or previous commands with `sudo` by pressing <kbd>esc</kbd> twice.
|
|
|
|
To use it, add `sudo` to the plugins array in your zshrc file:
|
|
|
|
```zsh
|
|
plugins=(... sudo)
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Current typed commands
|
|
|
|
Say you have typed a long command and forgot to add `sudo` in front:
|
|
|
|
```console
|
|
$ apt-get install build-essential
|
|
```
|
|
|
|
By pressing the <kbd>esc</kbd> key twice, you will have the same command with `sudo` prefixed without typing:
|
|
|
|
```console
|
|
$ 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`:
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ sudo -e /etc/hosts
|
|
```
|
|
|
|
### Previous executed commands
|
|
|
|
Say you want to delete a system file and denied:
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```sh
|
|
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.
