I have a doubt. I create a wrong tag. I want deleted but i dont know if is a bad idea. If i delete the tag i will delete some code? I think no, but i dont sure…
No, you won’t delete any code, you will only delete the tag. The only reason to be cautious, is if you think someone else might have that tag in their local clone of your repo, and they might be relying on it. If you are sure that isn’t the case, then I think you’ll probably be OK!
If you are really paranoid though, make a repo to try these things out (I have one called
scratch for whenever I’m unsure about the effects of a change).
