tailf(1) -- Linux man page
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 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.
BUGS
An option could be provided to print out the last
n
lines instead of the last 10.
