Version: Oracle Linux 6.6
I was trying to shutdown Oracle Linux OS using shutdown -h command. But, I got the below error.
[root@pravda178 ~]# shutdown -h
shutdown: time expected
Try `shutdown --help' for more information.
[root@pravda178 ~]#
poweroff command works. But it is not a graceful shutdown apparently.
Why am I getting the above error ?
How to gracefully shutdown Oracle Linux OS ?
