inlined the link for the Git documentation + minor fixes
  • With `git reset`, but first you may want to save the current state in another branch:
  • ```bash
  • $ git switch main
  • $ git branch backup-of-main
  • ```
  • Now the (perhaps messed up) state is safely stored in branch `backup-of-main`, and you can always just switch back to it and have another swing.
  • To move `main` to an earlier commit: [[1]](https://git-scm.com/docs/git-reset#Documentation/git-reset.txt-emgitresetemltmodegtltcommitgt)
  • ```bash
  • $ git switch main
  • $ git reset --hard <commit-hash>
  • ```
  • Now you might still run into issues when pushing main to a remote which has already seen the more futuristic states. In this case you need to force push:
  • ```bash
  • $ git push --force
  • ```
  • When you are _absolutely sure_ that it worked out as you planned, you may consider removing the `backup-of-main` branch. See [this question](https://software.codidact.com/posts/289829) for how.
