TAILF(1) User Commands TAILF(1)

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 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.

       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.
