Remote tracking branches, and how they work.

• master: local tracking branch
• origin/master: remote tracking branch
• master on remote system: remote branch

All of these branches can be “out of sync” with one another.

Examples using the Linux kernel source repository.

$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

$ git show master
