github head detached fix code example

Example: git fix detached head

2388

Detached head means you are no longer on a branch, you have checked out a single commit in the history (in this case the commit previous to HEAD, i.e. HEAD^).

If you want to delete your changes associated with the detached HEAD
You only need to checkout the branch you were on, e.g.

git checkout master
Next time you have changed a file and want to restore it to the state it is in the index, don't delete the file first, just do

git checkout -- path/to/foo
This will restore the file foo to the state it is in the index.
