I did not realize I've been working on a detached HEAD (a32b42b123) branch until now. This branch is falling behind master a lot. I did the following operations, git checkout master && git pull origin master git checkout a32b42b123 && git rebase master to sync up this branch with master and noticed most of the changes I made in this branch are gone. Now I understand what a detached HEAD is. But how could I perform the git rebase master safety here without wiping out the change I made?
