Which command shows what currently logged-in users are doing?

• A. who
• B. users
• C. w
• D. finger

Answer: (C)

Seeing what currently logged-in users are doing is about showing active sessions and the processes tied to them. The command that provides this view is w, because it prints a line per user that includes who they are, which terminal they’re on, when they logged in, how long they’ve been idle, and the command they’re currently running. This gives a real-time snapshot of user activity. In contrast, who lists only who is logged in and where/when, without the current activity; users outputs just usernames; and finger shows account details but doesn’t emphasize the exact command being executed. So, w is the best tool for seeing what each logged-in user is doing.
