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.
