How to get back to the latest commit after checking out a previous commit?

 If the commit (that you need to return) is known and you want that to attach with the head of some branch then use:

      git checkout 

And also you can see the commits that your HEAD has previously pointed to by using:

      git reflog

For the latest versions of git, if you had done any checkouts something to moving your HEAD

You can also do:

      git checkout -

This will take you back to the previous checkout. Thus, you can go back to the latest commits after checking out a previous commit.
