[git] How can I switch my git repository to a particular commit

To create a new branch (locally):

  • With the commit hash (or part of it)

    git checkout -b new_branch 6e559cb
    
  • or to go back 4 commits from HEAD

    git checkout -b new_branch HEAD~4
    

Once your new branch is created (locally), you might want to replicate this change on a remote of the same name: How can I push my changes to a remote branch


For discarding the last three commits, see Lunaryorn's answer below.


For moving your current branch HEAD to the specified commit without creating a new branch, see Arpiagar's answer below.
