Look, I appretiate that people answer my questions but why won't some
on tell me the answer to this question. I asume the last line in the
script does a yum update. But why is such a complex line needed.
Where does shell come from and what do the commands in:
do exactly.

The file /etc/init.d is a joke. All that to create a lock file for a
program it does not run, That is at least a minor violation of the
concept behind the scripts in /etc/init.d
