I tired using the 'usermod' commandto add my user to the sudoers file.
it did not work.
[root@new-host-3 FEDORA_CASPER]# su -c " usermod -g wheel FEDORA_CASPER"
The usermod command modifies the system account files to reflect the changes that are specified on the command line.
What files does the usermod command change - because it was not the /etc/sudoers file.
also what is the wheel and why i had to use the -c (command) flag
[FEDORA_CASPER@new-host-3 ~]$ cat /etc/issue
Fedora release 20 (Heisenbug)
Kernel \r on an \m (\l)
I ended up adding my user to the /etc/sudoers file with visudo command - is this ok?
Is this how you add users to the Fedora system?
su [options] [-] [user [argument...]]
su allows to run commands with a substitute user and group ID.
Pass command to the shell with the -c option.
