Again, running in these branches git pull will fetch all remote indexes and merge their data into the local branch.
When cloning a repository, Git usually automatically creates a master branch called origin/master. That's exactly why git push and git pull works fine in the first place. Of course, you can set other tracking branches as you like, such as other branches other origin than master the ones above. We have just seen an example of this: git checkout -b [分支名] [远程名]/[分支名]. If you have Git version 1.6.2+, you can also --track simplify with options:
