tailf is deprecated. It may have unfixed bugs and will be removed
from util-linux in March 2017. Nowadays it's safe to use tail -f
(from coreutils), in contrast to what the original documentation
tailf will print out the last 10 lines of the given file and then
wait for this file to grow. It is similar to tail -f but does not
access the file when it is not growing. This has the side effect of
not updating the access time for the file, so a filesystem flush does
not occur periodically when no log activity is happening.
tailf is extremely useful for monitoring log files on a laptop when
logging is infrequent and the user wishes the hard disk to spin down
to conserve battery life.
