One of the features of multi-user operating systems, which include Linux, is the ability to be used by different people. Usually, a separate account is created for each of them. In Linux, the list of users can be viewed using the shell by entering a special sequence of characters. This solution to the problem is the simplest and does not require the use of special skills.
