The -uoption does the following: For every branch that is up to date or successfully pushed, add upstream (tracking) reference, used by argument-less git-pull and other commands.
的-u选项执行以下操作：对于每一个分支是最新的或成功推，添加上游（跟踪）参考，由参数少的git拉丝及其他命令使用。
So, after pushing your local branch with -uoption, this local branch will be automatically linked with remote branch, and you can use git pull without any arguments.
因此，在使用-u选项推送本地分支后，此本地分支将自动与远程分支链接，您可以不带任何参数使用 git pull。

It's the same as --set-upstream
它与 --set-upstream
It's used to set origin as the upstream remote in your git config.
它用于在您的 git 配置中将 origin 设置为上游远程。
It may help if you don't want to manually specify the remote every time you run git push.
如果您不想在每次运行 git push 时手动指定遥控器，这可能会有所帮助。
