修改 pull 的默认配置为 rebase
git pull = git fetch + git merge
执行 git pull 命令时，默认是用 git merge 来合并代码的。大家都知道，用 merge 合并代码的节点不在一个分支上，不方便查看节点信息，所以很多公司是采用 git rebase 来合并代码的。针对这种情况，可以在自己的电脑终端，修改 git 的全局配置，将 pull 的默认配置改为 rebase。
全局修改 pull 的命令：

git config --global --add pull.rebase true 划重点！！！

查看是否修改成功命令:

git config --global -l
