How to make password show asterisks as I type it when running `sudo` command?
Open your terminal and edit /etc/sudoers.tmp file with:
sudo visudo
Modify the following line:
Defaults env_reset
to:
Defaults env_reset,pwfeedback
Save and exit.
Restart your terminal and now, when you run a command with sudo, you should get visual feedback when you type in your password.
