Which utility displays information about a user on a remote system, including last log-in time and username, and is commonly used in Linux?

• A. finger
• B. whoami
• C. last
• D. uname

Answer: (A)

Think about a command that provides account details for a user, including who they are (username) and when they last logged in. finger is designed for exactly that: it displays information about user accounts on a system, and when querying a user on a remote host it can show the username and the last login time, along with other basic details about the account. It’s the go-to tool for quick per-user information across local or remote systems. In contrast, whoami only prints the current user’s login name, not information about other users. last shows recent login records for all users, not the details of a specific user on a remote system. uname reveals system information like the kernel and hardware, not user account data.
