NAME
       tailf - follow the growth of a log file

SYNOPSIS
       tailf 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 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 desires that the hard disk spin down to
       conserve battery life.

BUGS
       An option could be provided to print out the last n lines instead of the last 10.
