NAMEtailf - follow the growth of a log file
SYNOPSIStailf [option] file
DESCRIPTIONtailf is deprecated. It may have unfixed bugs and will be removed in March 2017. Nowadays it's safe to use tail -f (coreutils) in contrast to the original documentation below.
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.
