TAILF(1) User Commands TAILF(1) 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. -V, --version Output version information and exit. -h, --help Display help and exit.
