Arch Linux: Sudoers

Sudoer files is the configuration file for sudo command. It is located at /etc/sudoers.

Editing Sudoer

It MUST be edited using the command sudo visudo. Behind the scenes this command creates a temporary file, checks for any errors once you save and finally replace the original file.

However editing in vi can be a pain. You can change it to any terminal editors using the command in the form below.

su
VISUAL=nano visudo

In case that is not working, you can symlink nano to vi

sudo ln -s /usr/bin/nano /usr/bin/vi
sudo visudo

Some changes made to configuration are as follows:

Defaults passwd_timeout=0
Defaults passprompt="^G[sudo] password for %p: "
Defaults insults

1. Do not timeout when asking for password. Especially helpful when running commands like yay -Syu where password is asked only after downloads are done and if you do not type password within some time, it will timeout.
2. Prompt Template for password - ^G is a bell symbol so it will alert you.
3. Throw insults if the password is wrong
