The command tail -F -n 5 /var/log/webserver.log addresses the question's requirements by using -F (capital F), which not only outputs the last five lines of the file with -n 5 but also monitors the file descriptor in case the log file is rotated, as is common with log management. This is useful for system administrators who want to ensure that the monitoring script continues to function even if the original log file is archived and a new one is created. The wrong answers either don't follow the file descriptor changes (tail -f -n 5), don't provide real-time monitoring (tail -n 5), or lack specificity in tracking the correct number of lines (tail -F).
