TAILF(1)                         User Commands                        TAILF(1)

NAME
       tailf - follow the growth of a log file

SYNOPSIS
       tailf [option] file

DESCRIPTION
       tailf  is  deprecated.  It may have unfixed bugs and will be removed in
       March 2017. Nowadays it's safe to use tail -f (coreutils)  in  contrast
       to the original documentation below.

       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 desires that the hard disk 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.
