What does ::pause >nul mean/do? (in batch)

Question

I'm currently working on an AI in batch, I've used ::pause >nul before but I'm not exactly sure what it does. All answers are appreciated

Solution

• :: means that the current line is a comment (it actually is an invalid label which works the same as a comment)
• pause pauses the script untill the user presses a key
• >nul redirects output to nothing.

This means that this is an outcommented pause that doesn't show the press any key to continue . . . message to the screen, so it doesn't do anything.
