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 peri-
odically 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.
