Disable sudo timeout on Ubuntu in terminal

By default sudo remembers your password for 15 minutes.

Disable sudo timeout with this command:

sudo sh -c 'echo "\nDefaults timestamp_timeout=-1">>/etc/sudoers'

To re-enable sudo timeout use this command:

sudo sed -i "/Defaults timestamp_timeout=-1/d" /etc/sudoers

You can also change or disable sudo timeout with visudo.

sudo visudo

This opens an editor and points it to the sudoers file — Ubuntu defaults to nano, other systems use Vi.

To the defaults line, add :

timestamp_timeout=2

So it will look like this:

Defaults env_reset,timestamp_timeout=20

You might want to read the sudoers manual pages for additional information.
