Pipe output to file without removing from screen

I am writing  a script that I want to capture all STDOUT and STERR both. I know i can route both to screen with 2>&1, but....

I'd like both streams to go to the screen for viewing by person running the script, but I'd like to capture that output to a file at the same time as well, so I can send it to a logger tool.

Is this possible with piping magic?

Re: Pipe output to file without removing from screen

Try this (untested).

for /f "usebackq tokens=1* delims=:" %%a in (`yourcommand 2^>^&1 ^| findstr /n ".*"`) do (

  (<0 set /p "=%%b" & echo:) >&1
  (<0 set /p "=%%b" & echo:) >&2

) 2>> yourlogfile.txt

Not sure what behaviour you'll see if your command is expecting user input.
