How to pipe program output to the screen AND to a file under Windows

Question

I have a command which I need to inspect in real time (i.e. see its output in the command prompt MyProgram.exe) and to have a log file for later inspection (MyProgram.exe > log.txt)

How can I make a single instance of the program to write to both outputs?

Answer 1

Either use one of many tee clones for Windows.

Or if you're using PowerShell, you can use Tee-Object.

Answer 2

You want a unix tee clone like this one or this one. I'm sure there are others, but, well, your Google for 'windows tee' is as good as mine.
