Not sure on the order because I'm not sure what you mean. But typically you create groups first (using groupadd) and then add your user to the groups. If the user is new, something like:
useradd -g users -G wheel,etc,etc,etc -m ... jim

If the user exists, something like:
usermod -aG wheel,etc,etc,etc

Should work.

Good Luck!

The groups have to exist before you can add a user to them. So you make the groups you want, then create the user, and add them to the group. You didn't say what distro you are using. Some have tools to manage the creation of users and groups.

If you are new to linux, I would recommend you take the time to install Webmin. It is available for all distros. In Webmin, there is a Manage Users and Groups function. In here you can create new groups, add create new users, and add any user to any group that you choose. It is much easier to use than the command line tools. It is graphical, and as its name may imply, you can access Webmin locally through your web browser or from a remote location through a web browser.

I install it on all my systems, and then use it for management of most of the servers and configuration on each system. You need to create a webmin user in webmin. Once that is done, you can control what elements of the system you want any webmin user to modify. It can be everything, like root, or limited to one item. Root will have full privileges.

Hope this helps.

Some general hints to help you learn:

1) in a terminal, use the apropos command to help find commands: appropos group
would give you a list of all commands on your system having anything to do with group.

2) is your friend and largest resource for information on Linux-related issues.

3) the LQ forum has a search function. Use it frequently. Most problems you encounter have probably already been asked.

4) include in your post which distro you are using. The command-line tools will probably be the same for most, if not all, distros. But, each distro may have it's own set of GUI tools. Knowing the distro you use helps others with experience with that distro to give you helpful directions.
