How to remove an action after it's done?

Question

cmd/bat

There is a piece of code: explorer https://google.com
How to make sure that this part is deleted after the first launch? So that at the first opening it opens the specified site, and the subsequent ones no longer. Or create a new .bat with the specified code and delete itself

Answer 1

So far it's been like this:

explorer https://google.com& rem rnd_7brydbde
find /v "rnd_7brydbde" <"%~dpnx0" >"%~dpnx0.new"
move /y "%~dpnx0.new" "%~dpnx0" >nul & goto NEXT& rem rnd_7brydbde
:NEXT

Answer 2

Create a flag file (well, or vice versa - delete). And at startup, check for its presence. If it is, then we launch it without a website.

Answer 3

After the first launch, I would create a flag file, on subsequent launches, I would check for its presence, and launch / not launch the action.
