查看单个远程仓库时候的.git/config

一般而言，你的git项目的配置会是如下

[core]repositoryformatversion = 0filemode = truebare = falselogallrefupdates = true
[remote "origin"]url = https://github.com/yoda/skywalker.gitfetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]remote = originmerge = refs/heads/master

用命令添加其他的远程仓库

git remote add mirror https://gitee.com/yoda/skywalker.git

这时再查看.git/config文件，会发现文件内容变为

[core]repositoryformatversion = 0filemode = truebare = falselogallrefupdates = true
[remote "origin"]url = https://github.com/yoda/skywalker.gitfetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]remote = originmerge = refs/heads/master
[remote "mirror"]url = https://gitee.com/yoda/skywalker.gitfetch = +refs/heads/*:refs/remotes/mirror/*

从2个仓库分别拉取和推送

git pull origin master 
git pull mirror master
git push origin master 
git push mirror master

一条命令从2个仓库拉取推送也有办法，不过不太这么用，建议使用merge request，这里就不贴出来了。
