Recently installed SLES12. Planning to run a customized shell script as part of startup applications.

In SLES11 , We are able to achieve this task using control center ie wrote a shell script and launching the same using the Control center by adding into the startup Applications. But in SLES12, I was not able to found the control center and not able to add a custom script as a startup applications.

Please provide us the steps to achieve the same in SLES12.

Thanks in advance.
