I need to come up with a syntax that will enable and initialize TPM from the command in on a win7 system. We cannot use the gui as I will be doing this from a batch file.

I found the link below but there is not mention of initializing it. Can it be done?

Open powershell and type
gcm |sls tpm
this will show you the tpm-related commands, initialize-tpm is amongst them.

My bad, I am on win8.1, maybe on win7, that modules need to be imported, first.
import-module BitLocker
And also you Need to have the latest powershell, Version 4.

Does that mean I need to upgrade to PS 4.0 before running the TPM initialization command?

Exactly.
But you should find out what
manage-bde -tpm -turnon
does, maybe it includes initialization?

Oh, that won't work then. Means I would have to upgrade PS on about 3000 systems. Is there any other way?

Another way? As I wrote, see what exactly manage-bde -tpm -turnon does, maybe it can be done with that one, too.
And if you have 3000 Systems, why not deploy powershell4? https://4sysops.com/archives/deploying-powershell-4-with-group-policy/

Is the TPM on in BIOS?  Enabling that from the command line may not be possible.

I've played a little with the mange-bde and I believe what you want to do should be possible, however I have not done it myself (yet).

It is in the bios, but I guess it's possible to enable.

You did not follow my suggestion yet? PS4 is easily deployed, look at my link.
