Recently, I decided to replace most of the PowerShell code with batch file code in my appveyor.yml file. I had to put a for /f loop to parse the output of two commands and some more to parse textfiles. But this doesn't work. I have tried it both locally and in RDP and woking fine!

Some examples:

and some more similar examples. Why this happens only in the console and not locally or remotely?

    Please demonstrate where you think AppVeyor is not working via a minimal repro of the error.
    In this case, you can simply start a project with one single text file and run those commands in init stage.

    Just add another % to the loop parameter.

    for /f "delims=" %B IN ('ver') do echo %B
    for /f "delims=" %%B IN ('ver') do echo %%B

    Thanks for replying; it works fine. Why should I double percent-signs? My code isn't running from cmd?

    This has not attracted so much attention. Closing so...
