Is there a command window method to duplicate all variables in workspace

We can duplicate all the variables in the workspace by selecting all of them (CTRL-A), right clicking for options menu and choosing duplicate. Can we do this right from the command line itself?

Yes, it is possible. No, it is not likely to be a good idea:

Can you explain why you'd want to do that?
