tailf(1) -- Linux man page
NAMEtailf - follow the growth of a log file
DESCRIPTIONtailf 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.
BUGSAn option could be provided to print out the last n lines instead of the last 10.
