How to delete the content of github repository?

Question

I wrongly pushed my code using Xcode toolbar into my repository on github. now, I want to delete all files in my master branch, but not the repository. Then I want to pull my code into repository this time instead of pushing. Does any one know how to delete all contents of master branch?

Solution 1

In git, you can't delete the content of a branch. All you can do is to push a commit that removes all your files.
If you want to start over from a clean repository, you have to delete the current one a create a new one with the same name for example.

Solution 2

Just to support quentin's answer, adding the git commands:

1. Keep a backup of the local repository folder and remove all its contents.

2. Add these changes to commit

$ git add *

3. Add a Commit message

$ git commit "Remove everything"

4. Push changes

$ git push -f
