Tail-f is equivalent to-- follow=descriptor and is tracked according to the file descriptor. When the file is renamed or deleted, the trace stops.

Tail-F is equivalent to-- follow=name-- retry. Track according to the file name and keep retrying, that is, if the file is deleted or renamed, if you create the same file name again, the trace will continue.

Tailf is equivalent to tail-f-n 10 (it seems that tail-f or-F prints the last 10 lines by default, and then tracks the file). Unlike tail-f, it does not access disk files if the file does not grow, so tailf is especially suitable for tracking log files on laptops because it reduces disk access and saves power.
