Do not stop when end-of-file is reached, but rather to wait for
additional data to be appended to the input. If the file is re-
placed (i.e., the inode number changes), tail will reopen the
file and continue. If the file is truncated, tail will reset its
position to the beginning. This makes tail more useful for
watching log files that may get rotated. The -f option is ig-
nored if the standard input is a pipe, but not if it is a FIFO.
So, no -F or --retry but a different default behavior
