How To Output a Message to Both a File and Console

Hello,

In a DOS\Console batch file I need to output all information (standard output and error output) to both the screen AND a log type file.  Ideally I Do NOT want to use two lines every time I need to output a message (one to screen and one to file - yuk).  Here is an example output line:

set MYFILE=c:\temp\myfile.log
set FILE_TYPE=Export
echo %time% - Transferring %FILE_TYPE%

I know I can append this to a file using:
echo %time% - Transferring %FILE_TYPE% >> %MYFILE%

OR even

echo %time% - Transferring %FILE_TYPE% >> %MYFILE% 2>&1

My problem is if the above is used I do not get any screen output.  I feel I am close.

What can you suggestion?

Thanks,

You'll need a tool like tee.exe (I believe you can get it from here: http://www.weihenstephan.de/~syring/win32/UnxUtilsDist.html)

You can cheat a little too if you are unable to add tools such as tee.exe or don't have them to hand, i.e.

echo %time% - Transferring %FILE_TYPE% >> %MYFILE% 2>&1 & type %myfile%

but that isn't so handy when appending to a file like you are.... you end up with:

echo %time% - Transferring %FILE_TYPE% > %tempfile% 2>&1 & type %tempfile% & type %tempfile%>>%myfile%

and you might aswell use two lines.  Can come in handy sometimes though.
