I have forked a repository on github some time ago, made a small change and pushed the change back to my github fork. The original repository has changed since. I would like to merge the changes from the original repository to my fork.
I am new to both git and github, and I need specific commands how to do it.
Simply add original repo as a remote and merge your fork with it; then push merged fork to github.
There's also a ruby gem for easier github operations. You can merge upstream with one call...
git remote add {name} {Public Clone URL}
git pull {name} master
git push
Example:
git remote add bret git://github.com/bret/watir.git
git pull bret master
git push
