I need to switch users while performing a task, I am trying to do this with the following:

echo "pass" | sudo -u user | ls

However I can't seem to escape the prompt for the password, is there a way for this prompt not show up?

The /etc/sudoers file dictates who is allowed to sudo to what account.
When setup up correctly:

 sudo su - <someusername>
 ls 
 exit # get out of sudo

requires no password.

If you set up so that you or whoever is running the script can sudo then the script will run without a passwoird prompt.

There was some reason for the default behavior that I can't recall.
