TAILF

NAME

tailf – follow the growth of a log file  

SYNOPSIS

tailf [option] file  

DESCRIPTION

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.
