I'm running Manjaro Linux and I've got the following entries in my sudoers file:
$ sudo grep -vE '^#|^$' /etc/sudoers root ALL=(ALL) ALL %wheel ALL=(ALL) NOPASSWD: ALL
And my user is part of the 'wheel' group:
$ groups sys network power vboxusers lp wheel user
How come I still get asked for a password whenever I run sudo?
Also, suppose my username is 'user' and I only have
root ALL=(ALL) ALL in the sudoers file. This was the original setting and I was able to run sudo commands even though there is nothing defined for 'user' in this file. How does this work?
