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
- Zsh
# 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 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.
