Context: Generic GNU/Linux certification command examples.

Assign users to appropriate groups.

To assign users to appropriate groups in a GNU/Linux system, you can use the usermod command. Here are some examples:

1. Add a user to a specific group:

Replace groupname with the name of the group you want to add the user to, and username with the username of the user you want to assign.

2. Add a user to multiple groups:

Replace group1, group2, and group3 with the names of the groups you want to add the user to.

3. Remove a user from a group:

Replace username with the username of the user you want to remove and groupname with the name of the group from which you want to remove the user.

4. Create a new group and assign a user to it:

Replace newgroup with the name of the group you want to create and username with the username of the user you want to assign.

Remember to replace groupname and username with the appropriate values according to your system configuration.
