When you write a shell script need monitor log outputs, this feature is
essential.

Before we write this with syslog and tail.

"tail -fn0 /path/to/logfile | while read line ; do"

When using "journalctl -fn1 /path/to/sth", it will always give the last line of
the log, I have to write some extra processing it.

But I do not know how to handle it with a simple way, I just want handle the
new log line.

Sorry for my poor english.
