NAME
       tailf - follow the growth of a log file

SYNOPSIS
       tailf [OPTION] file

DESCRIPTION
       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  peri-
       odically 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 too.

       -n, --lines=N, -N
	      output the last N lines, instead of the last 10.

       -V, --version
	      Output version information and exit.

       -h, --help
	      Display help and exit.
