LPIC-1 Exam 101 (Linux Administrator) — Question 51

Which of the following commands can be used to determine how long the system has been running? (Choose TWO correct answers.)

Answer options

• A. uptime
• B. up
• C. top
• D. uname -u
• E. time up

Correct answer: A, C

Explanation

The command 'uptime' provides information on how long the system has been running, along with user load averages. The 'top' command, while primarily for monitoring processes, also displays the system's uptime at the top of its interface. The other options do not provide this information, making them incorrect.
