Determining if batch script has been started/executed from the command line (cmd) -or- To pause or not to pause?

Question

I like to have a typical \"usage:\" line in my cmd.exe scripts — if a parameter is missing, user is given simple reminder of how the script is to be used.

Start your batch checking for %WINDIR% in %cmdcmdline% like this:

echo "%cmdcmdline%" | findstr /ic:"%windir%" >nul && (
  echo Interactive run of: %0 is not allowed
  pause
  exit /B 1
)
