Configuring to detect if a command does not exist, suggest installation
Can the zsh
shell be configured to show what bash
shows when a command does not exist, similarly to this:
kahless:~$ sysv-rc-conf
The program 'sysv-rc-conf' is currently not installed. You can install it by typing:
sudo apt-get install sysv-rc-conf
rather than the ZSH prompt:
[kahless /home/teward]% sysv-rc-conf
zsh: command not found: sysv-rc-conf
Note I do not want to change the prompt itself, but I want to change the result from zsh: command not found
to a bash-like output of The program 'progname' is currently not installed. You can install it by typing:
or similar.
Is this possible with ZSH?
This feature is provided by the command-not-found
package. Ubuntu installs it by default, and makes it active by default in bash but not in zsh. Just add this line to your ~/.zshrc
:
. /etc/zsh_command_not_found
Note that you might want to add a check if the file exists if you are sharing your .zshrc across distributions that do not have a /etc/zsh_command_not_found
file:
[[ -a "/etc/zsh_command_not_found" ]] && . /etc/zsh_command_not_found
Also, in case you're using oh-my-zsh, there already is a plugin, command-not-found
, that you can add to your plugins
variable that does the same thing.
If you are using oh-my-zsh, you can just instead looks for "plugins" inside your .zshrc
.
Add the command-not-found
plugin to the list of plugins to autoload (this plugin is already installed by default).
Like this:
# Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*)
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
plugins=(git command-not-found)
