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
- Bash v4 and newer
# 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 (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.
bash-insulter can be customized, or even be made polite and nice, by populating
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.
