bash-insulter

Randomly insults the user when typing wrong command.

Change insults as needed :)

noob@bender:~ $ sl



  Y u no speak computer???



-bash: sl: command not found

noob@bender:~ $ gti status



  This is why nobody likes you.



-bash: gti: command not found

noob@bender:~ $ sp aux



  Go outside.



-bash: sp: command not found

Compatibility

• Bash v4 and newer


• Zsh

Installation

# Method 1 - know what you are doing

git clone https://github.com/hkbakke/bash-insulter.git bash-insulter

sudo cp bash-insulter/src/bash.command-not-found /etc/



# Method 2 - I don't care, insult me!

sudo wget -O /etc/bash.command-not-found https://raw.githubusercontent.com/hkbakke/bash-insulter/master/src/bash.command-not-found

Then source the file automatically for new logins by adding the following to /etc/bash.bashrc or any of the other locations where you can configure your shell automatically during login:

if [ -f /etc/bash.command-not-found ]; then

    . /etc/bash.command-not-found

fi

Login again and type some invalid commands for the effects to be visible.

Note: You will have to add the script to .zshrc if you are using zsh

Configuration

bash-insulter can be customized, or even be made polite and nice, by populating CMD_NOT_FOUND_MSGS or CMD_NOT_FOUND_MSGS_APPEND environment variables. The values should be arrays. CMD_NOT_FOUND_MSGS replaces the default messages, while CMD_NOT_FOUND_MSGS_APPEND appends more messages to the existing ones.

It is probably cleanest to source a file populating the environment variable as needed. In this example I create a file /etc/bash.command-not-found-messages with the following content:

CMD_NOT_FOUND_MSGS=(

    "You are so smart!"

    "You look pretty today!"

    "I don't know what to say"

)

Then source this file before you source the script:

if [ -f /etc/bash.command-not-found-messages ]; then

    . /etc/bash.command-not-found-messages

fi



if [ -f /etc/bash.command-not-found ]; then

    . /etc/bash.command-not-found

fi

Then logout and in again. The end result is that you will now use your messages instead of the default ones.
