What are the difference between tail -f and tail -F?
Answer:
Basically these two command are very similar, except tail -F do one more thing: the retry.
This is useful when you are tailing a web server log, e.g. apache log. When the the log file got rotated, the tail -F will continue to work since it will retry for the rotated file, while tail -f can't.
