Not enough time!

When you use sudo in Linux, a session that lasts 15 minutes by default, is created. This may be not enough time for a user to complete a task as root, in my case, everytime QownNotes package is updated (usually every day!) it last more than this time to finish it compilation process, so I need to reenter my password, but when this terminal window is in the background the time for asking the password also expires and I need to restart the update process.


How to make sudo sessions last longer

This is a really easy, you just need to use visudo tool

sudo visudo

and change the line:

Defaults env_reset


Defaults env_reset,timestamp_timeout=30

Where, of course, timeout=30 refers to the number of minutes you want the session to be available. You can also change this value to 0 if you want to ask for the password every time sudo is used, or use -1 in case you don’t want to ask for the password at all.



If you don’t like to be blind when typing your passwords in the terminal, you can also add a little ‘hack’ when editing /etc/sudoers to make the shell show you asterisks instead of a desert of emptiness 🙁

sudo visudo


Defaults env_reset,pwfeedback
Now when you use sudo command you will see cute asterisks!


All in one

Finally, you maybe would like to include all this in a script so here it is:


echo 'Defaults env_reset,pwfeedback,timestamp_timeout=30' | sudo EDITOR='tee -a' visudo
Cool, isn’t it?
