Instructions
Step 1
To add a user to a Linux group, first create it. All actions related to setting up user groups and other operations for performing actions related to computer management are performed using the console.
Step 2
Enter the useradd command into it. Also, using this command, you can update the data about the current user. To add a user to an existing group, the command text will look like this: # useradd -G Name username.
Step 3
Replace username with the name of the user you created or an existing one that you want to add to the group, replace Name with the name of the group. The file responsible for group operations and lists of group users are located in the / etc / passwd, / etc / shadow and / etc / group directories.
Step 4
If you want to pre-create a group, use the groupadd command that is entered into the console. In this case, the full text will look like this: # groupadd linux name. Replace name with a group name of your choice.
Step 5
To remove a user from a group on Linux, use the following command: # cat / etc / group | grep username. Instead of username, of course, enter the username if you know it.
Step 6
If you are a computer administrator and are not familiar with the commands for managing accounts or are simply not a confident user of this software, use the special training literature. It is also possible to install several operating systems on one computer in the event that you are experiencing certain difficulties with one Linux operating system. You can also get information you are interested in on special thematic forums dedicated to Linux.
