I've created a batch file with the following code:

xcopy f:\ c:\backupFolder /E /S /I /Y

How do I code this batch file to show the DOS window copying all the files (which it does automatically) but also output that same list of files (exactly what it shows in the DOS window) to a text file in C:\backupFolder? I know how to redirect the output, but I want it to output to both places (screen and text file) without running the command twice. Thanks in advance!

Maybe have it output to a buffer file, then print the contents of that file, before appending it to your record file? Though I guess you aren't immediately informed of progress if you use such means...

I haven't tested it, but I think all you need to do is to redirect your console output to a file like so:
/complete command/>>c:\backupfolder\xcopy.log

Give it a try and see if that works.

@Jabo: that will preclude displaying the output to the screen (unless an error occurs, as that will probably go to stderr instead of stdout). The OP wants to do both, and besides the buffer to file, then echo said file, I can't think of any easy choices. I suppose you could write a program to pipe XCOPY's output to, and this program would read from stdin and write to both stdout and the file you specify, but that's probably overkill for this situation.

The unix tee command does just what you want. Here is a windows version. Its more than likely to be implementd similar to the previously posted program.
