Run batch script showing output & recording output to a file

Question

I know cmd > file.txt to record an output of a command to a file in Windows!.

Does anybody know how to run a batch script recording the output to a file AND also showing the output on the command prompt as well when executed?

You'll need a Windows-based implementation of tee to do this. Here are some options:

If you don't require output in situ, you can "cheat" by piping the commands, but this is not nearly as useful as following stdout in real-time.

cmd >file.txt | type file.txt

	I thought of using your easy method `cmd >file.txt \| type file.txt` but it's showing the copy percentage as 0%(not updating) till the end. I'm trying to install `wintee`, didn't get correct link yet. Trying... – user53864 Jul 23 '11 at 5:58
	@user53864 Yes, the redirection+pipe doesn't work quite like `tee`, as the first command must complete entirely before the `type` will occur. The code.google.com link in my answer is a working version of `wintee` -- is it non-functional for you? – jscott Jul 23 '11 at 10:38
	That `wintee.exe` just opening and staying like a statue when I double clicked to execute it. – user53864 Jul 23 '11 at 12:40
	@user53864 It is a command-line program, not a windowed one. Try `wtee.exe --help` for usage. Using your question's example, you'd want to do `cmd \| wtee.exe file.txt` to see the output on stdout as well as redirect it to `file.txt`. – jscott Jul 23 '11 at 12:47
	Oh...no. Actually I was using `cmd \| tee file.txt` instead of `cmd \| wtee file.txt`. That was my mistake which you corrected it. I thought I should install wtee.exe file by double clicking it but as you said it's not and instead should directly place it under system32. Thanks a lot!! – user53864 Jul 23 '11 at 15:44
