OK, that means that git reset --hard $( git log --reverse --pretty=tformat:%H | head -1 ) will reset the HEAD branch, the index, and the working directory to the "first" commit on the HEAD branch. But you should first think through that that is what you really want to do, i.e., to go back to that particular state of things and throw away all changes after that.

Unfortunately, git log -r -1 lists the last (HEAD) commit contrary to what I would naturally expect. I do understand the reason why it works as it does but oh well... ;-) -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.

Assuming that you want to reset the HEAD branch and the working
directory to be in the state of the first commit, the command would be:
git reset --hard {first-commit-hash}
As far as I know, there is no syntax to identify the oldest commit on
the current branch. But
git log --pretty=tformat:"%h %ai %s"
will list all the commits that are part of the current branch, and from
those you can select the hash of the oldest one.

I think you need to think about what you want to achieve a bit harder: to roll back what exactly? All the commits in any Git repository form one or more (directed, acyclic) graphs, and a commit is said to exist in a repository only if it is referenced, directly or indirectly, by one of entry points to those graphs. Entry points are branches and tags, so to have a repository with the single existing commit you have to make sure all the branches and tags existing in that repository point to that single commit. If, instead, you wanted to reset just a single branch to contain just that commit, you just do use `git reset` to make that branch point to that commit. Consider reading [1] to learn about how the `git reset` command works. 1. http://git-scm.com/book/en/v2/Git-Tools-Reset-Demystified -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.
