Detect if bat file is running via double click or from cmd window

I have a bat file that does a bunch of things and closes the cmd window which is fine when user double clicks the bat file from explorer. But if I run the bat file from a already open cmd window as in cmd>c:\myfile.bat then I do not want the bat file to close the cmd window (END) since I need to do other things. I need bat dos command code that will do something like

if (initiated_from_explorer) then
else
endif

Is this possible ? thanks

%cmdcmdline% gives the exact command line used to start the current Cmd.exe.

• When launched from a command console, this var is "%SystemRoot%\system32\cmd.exe".
• When launched from explorer this var is cmd /c ""{full_path_to_the_bat_file}" ";
  this implicates that you might also check the %0 variable in your bat file, for in this case it is always the full path to the bat file, and always enclosed in double quotes.

Personally, I would go for the %cmdcmdline% approach (not %O), but be aware that both start commands can be overridden in the registry…
