Made a commit on the wrong branch? Use git log to get the commit reference:
$ git log --graph --oneline
* dfa74cb (HEAD -> develop) Git - Cherry-Pick
* 91f1f59 (master) Git - Recover Dropped Stash
You can switch to the branch, and then use cherry-pick to apply the commit:
$ git checkout master
$ git cherry-pick dfa74cb
Which results in:
$ git log --graph --oneline
* 3301505 (HEAD -> master) Git - Cherry-Pick
* 91f1f59 Git - Recover Dropped Stash
If you don't want to commit the changes straight away, use git cherry-pick -n <ref> to just stage the changes instead.
