tailf(1) -- Linux man page



tailf - follow the growth of a log file  


tailf file  


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.  


An option could be provided to print out the last n lines instead of the last 10.
