TAILF(1)                   Linux Programmer’s Manual                  TAILF(1)




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 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.


BUGS

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