tailf - follow the growth of a log file


   tailf [option] file


   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 below says.

   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.

   -n, --lines=number, -number
          Output the last number lines, instead of the last 10.

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

   -h, --help
          Display help text and exit.
