Perhaps in ubuntu, it is defaults to use sudo to execute command as super user. But in fedora usually use “su -c” to execute command as super user. But if you want to use ubuntu style, don’t worry. Just do some simple step to make it happen.

1. Add user to a group, in this example “wheel”

$ su -c "useradd -g wheel user"

2. Edit visudo

$ su -c "visudo"

and uncomment this line

%wheel  ALL=(ALL)       ALL

or if you want to make user use sudo without password, uncomment this line (warning)

%wheel         ALL=(ALL)       NOPASSWD: ALL

3. Finish, you can use sudo to execute command as super user instead

$ sudo yum update

$ sudo gedit /etc/yum.conf
