如何将旧版本合并到git中的分支负责人？

Question

My repository has 2 branches, master and mybranch . I've commited many times into mybranch , realized that many of my changes were not what I wanted.

Thus, I did a git checkout of an old commit on* mybranch* using

git checkout 02c383

I want this old commit to be the HEAD of mybranch . How do I do this?

When I look at my branches, I see:

$ git branch
*(detached from numbershere)
mybranch
master

Answer 1

git checkout mybranch
git reset --hard 02c383

After this, mybranch will be moved to point to 02c383 .

Answer 2

You can reset the current branch to a different commit with

git reset --hard <ref>

In your example, this translates to

git reset --hard 02c383

Beware that

• you should avoid doing such things (esp. when mybranch is already used by others)
• getting back to the previous commit to which mybranch pointed before (which is now a dangling commit becomes a bit tricky, if you can't remember that SHA.
