Question

Well, I have this program that I run with the help of batch. Its a PHP script that is ran by an EXE file.
How can I have it that while the program is running, the output is automatically sent to a file, say log.txt, and have the output simultaneously shown on screen?

I tried something like program.exe >> log.txt, but that didnt show output on the screen.

If you want to do it only with windows commands may be you should try something like this:

program.exe > %temp%\temp.log
type %temp%\temp.log
type >>  log.txt
@del %temp%\temp.log /S /Q

there is no tail equivalent in windows commands.
