Tailf, Tail-f, tail-f three differences

Tail-f is equivalent to--follow=descriptor, tracking according to the file descriptor, when the file is renamed or deleted, the trace stops

Tail-f is equivalent to--follow=name--retry, tracked according to the file name, and remains retried, that is, after the file has been deleted or renamed, if you create the same file name again, you will continue to track

TAILF is equivalent to Tail-f-N 10 (seemingly tail-f or-f default also prints the last 10 lines, and then trace the file), unlike Tail-f, if the file does not grow, it does not go to access the disk files, so TAILF is particularly suitable for those portable computer tracking log files, because it is reduced Less disk access, can save power
