I am looking for a way to output CPU usage percentage via the command line. I ran across this: wmic cpu get loadpercentage which gives me the desired percentage output however I want to test the CPU usage while running a certain command. Anyone have any idea? I tried doing it in a batch file but then realized that at the point i run wmic cpu get loadpercentage the CPU usage is no longer portraying the usage of the previous command. Ideally what I am looking for is something like this:

C:\> command xyz [ftp file.blah]
and then the file is uploaded correctly but the output is a percentage indicative of the CPU usage during the process. Not sure if I'm making myself clear. Hopefully something like this exists out there. Thanks in advance!
