I can not shut down or restart my MBP except by pressing the power button. It will go to sleep OK, but not shut down or restart with normal commands.
MacBook Pro, OS X Yosemite (10.10.5), external monitor, external drives
Open Users & Group preferences and create a new, temporary admin user account. Restart the computer and log into this new account. Now, try to do a normal shutdown. If you can, then the problem you are having is related to applications or utilities you are loading and/or problems with preference files, log files, or cache files that have become corrupted.

Thanks Kappy. That worked. Now how do I 1. see which apps are starting up in my adm. log in and how do I get rid of the one or ones that are causing the problems, I suspect that I will have to stop each one, one at a time to see which one causes the problem, but not sure how I do that.
Well, this is the difficult part. I don't know which takes the less time: transferring files to a new user account or tracking down the culprit. You might start by booting back into your normal account. Open Users & Groups preferences, click on the Login Items tab and remove all the entries. Note down the names of each of the items in that list as you remove them. Restart the computer then try a shutdown. If it shuts down properly then the problem is due to one of the items in the Login Items list. Most likely a third-party item. On the other hand if nothing changes, then Login Items aren't causing the problem. Now, you need to shift to the applications you normally would have running. Open one at a time testing after each to see if one of them is the cause of the problem.
On the other hand you can stay in the new account and transfer only your data files over to the new account. For this to work see: Transferring files from one User Account to another. Do not transfer anything from the /Home/Library/ folder as this likely contains the corrupted file(s).
Thanks, I try tracking down the suspect first, I want to know what's causing this so I can keep an eye out for it in the future. Otherwise I may develop the problem again. This will take some time.
