tailf [OPTION] file
tailf will print out the last 10 lines of a file and then wait for the
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 periodi-
cally when no log activity is happening.
tailf is extremely useful for monitoring log files on a laptop when
logging is infrequent and the user desires that the hard disk spin down
to conserve battery life.
Mandatory arguments to long options are mandatory for short options
-n, --lines=N, -N
output the last N lines, instead of the last 10.
Output version information and exit.
