Then run some sudo command eg: sudo dnf update. usermod -aG wheel Joey Test the new user by login in as follows: Switch to the new user you’ve created. The process for giving users sudo privileges on Ubuntu and related systems is only a little different. Add the new user, Joey to the wheel group so that it can assume root privileges using the sudo command. In addition, if the user runs one command using sudo, additional sudo commands can be run without requiring the password to be supplied again for something like 15 minutes. $ sudo dateĪfterwards, the user will be able to run arbitrary commands with root privilege. Notice that the command requires that users supply their passwords. Given the setup just described, any command can be run as root using sudo. ![]() Note that one doesn’t need to run a privileged command to verify that sudo works for them. Once sudo privileges have been assigned in this way and verified, the user should be able to run some tests and verify that the sudo command works as expected. The process of assigning someone sudo privileges often starts with setting up the user’s account if it doesn’t yet exist, verifying the account and assigning a password (generally a temporary one) with commands like these:Īfterward, you can add the user to the wheel group and verify the addition with commands like these: $ sudo usermod -aG wheel newuser While that might seem like an odd name for the group that provides root-level privilege, it appears to have been derived from the term “big wheel” that was used for many years to describe someone with considerable power or influence. To provide a user with sudo privileges on Fedora and related systems, the user must be made a member of the “wheel” group. Doing routine work using the root account is considered dangerous because any typos or commands run in the wrong location can have very serious consequences. This is consistent with the policy that says root privilege should only be used as needed and that no one should simply log in as root and run all of their commands. However, the more important point is that it allows individuals to manage Linux systems – adding accounts, running updates, installing applications and backing up the system – without requiring these things be done using the root account. You might say that it allows users to run privileged commands without logging in as root, and that is true.
