Displaying Windows command prompt output and redirecting it to a file

How can I run a command-line application in the Windows command prompt and have the output both displayed and redirected to a file at the same time?

If, for example, I were to run the command dir > test.txt, this would redirect output to a file called test.txt without displaying the results.

How could I write a command to display the output and redirect output to a file in the Windows command prompt, similar to the tee command on Unix?

Solution 1:

To expand on davor's answer, you can use PowerShell like this:

powershell "dir | tee test.txt"

If you're trying to redirect the output of an exe in the current directory, you need to use .\ on the filename, eg:

powershell ".\something.exe | tee test.txt"

Solution 2:

I was able to find a solution/workaround of redirecting output to a file and then to the console:

dir > a.txt | type a.txt

where dir is the command which output needs to be redirected, a.txt a file where to store output.

Solution 3:

There's a Win32 port of the Unix tee command, that does exactly that. See http://unxutils.sourceforge.net/ or http://getgnuwin32.sourceforge.net/
