How can you view your login history in a Linux system?

• A. Using the `whoami` command
• B. Using the `login` command
• C. Using the `last` command
• D. Using the `history` command

Answer: (C)

Viewing your login history on a Linux system can be efficiently accomplished using the command. This command reads from the file that logs all user login sessions, presenting them in a chronological order. It includes details such as the username, the terminal used, the IP address of remote logins, and the timestamps of login and logout events. The `whoami` command simply displays the current user's username, making it unsuitable for checking login history. The `login` command is related to user sessions but does not provide history information—it is used for logging into user accounts. The `history` command lists commands that have been executed in the shell by the current user during the session or past sessions, but it does not track login events. Thus, using the `last` command is the most appropriate method to review login history in a Linux environment.
