1. Check the /etc/passwd file.
The /etc/passwd file contains a list of all the users on the system. Each line in the file contains a single user’s information, including their username.
2. Use the getent command.
The getent command can be used to query the system databases (such as passwd, group, and shadow). By running the command getent passwd you can get a list of all the users on the system, including their username.
3. Use the id command.
The id command can be used to get information about a specific user. If you know the user’s UID (User ID) or GID (Group ID), you can use the id command to get the user’s username.
4. Use the whoami command.
The whoami command will print the username of the user that is currently logged in.
