It is similar to +.B 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. +.PP +.B 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. +.PP +Mandatory arguments to long options are mandatory for short options too. +.TP +\fB\-n\fR, \fB\-\-lines\fR=\fIN\fR, \fB\-N\fR +output the last +.I N +lines, instead of the last 10. +.TP +\fB\-V\fR, \fB\-\-version +Output version information and exit. +.TP +\fB\-h\fR, \fB\-\-help +Display help and exit. + +.SH AUTHOR +This program was originally written by Rik Faith (faith@acm.org) and may be freely +distributed under the terms of the X11/MIT License.
