6 tailf - follow the growth of a log file

9 tailf [OPTION] file
10
12 tailf will print out the last 10 lines of a file and then wait for the
13 file to grow. It is similar to tail -f but does not access the file
14 when it is not growing. This has the side effect of not updating the
15 access time for the file, so a filesystem flush does not occur periodiā
16 cally when no log activity is happening.
17
18 tailf is extremely useful for monitoring log files on a laptop when
19 logging is infrequent and the user desires that the hard disk spin down
20 to conserve battery life.
21
22 Mandatory arguments to long options are mandatory for short options
23 too.
