Insults the user when typing wrong command

😛 bash-insulter-tanglish

Randomly insults the user when typing wrong command.

Change insults as needed :)

Inspired from this

mrcodekiddie@fossfreaks:~ $ lss

  Athukula ni seri patu varamataa

-bash: sl: command not found
mrcodekiddie@fossfreaks:~ $ gti status

  Thooku matikooo

-bash: gti: command not found
mrcodekiddie@fossfreaks:~ $ sp aux

  Sethuruuuuu...

-bash: sp: command not found

Compatibility

• Bash v4 and newer
• Zsh

Installation

# Method 1 - know what you are doing
git clone https://github.com/praba2210/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/praba2210/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 (zsh have different config files):

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.

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=(
    "Nallavada niii"
    "power button haa amikitu odi poiduu"
    "karumamdaa"
)

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.
