Add User on Linux

On Linux Operating System, one with root permission is allowed to create General Electric Comprehensive Operating Supervisor (GECOS) user account for normal usage. In this section, it guides you on how to create such user account.

Create Group

To create group, you simply use adduser command. The idea is:

$ adduser <username>

Here is an example:

$ adduser testo

Once done, you can check the creation status by getting the user again. Keep in mind that since Linux uses GECOS user management system, the creation will ask a number of information (through not necessarily to fill in all).

As a privacy advocate, I suggest you leave them out and use a more modern address book tracking system to query those user information. The maximum information you should fill in is "Full Name" only for identification query usage. The rest can be left out.
