Feedback when typing password at a sudo prompt
On some UNIX-based systems, sudo can show an asterisk (*) when you type a letter.
In the terminal, enter...
sudo visudo;
Type your root password in (you won't see any visual feedback yet) and hit Enter.
Now, find the line that reads:
Defaults env_reset
And replace it with:
Defaults env_reset,pwfeedback
Finally save and exit the file. Assuming you are using vi, that command is:
:wq!
and then press Enter.
sudo should now be set up correctly. To test, open up a new terminal and type this to reset the sudo timeout.
sudo -k;
Now try it out.
sudo ls;

You can enable visual feedback when typing passwords by editing your /etc/sudoers
file and changing the Defaults
line to read:
Defaults env_reset,pwfeedback
