TAILF(1)                   Linux Programmer's Manual                  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 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.

       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.
