1、一条命令同时更新多个远程仓库

直接在 .git/config 中添加远端地址

[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
	ignorecase = true
	precomposeunicode = true
[remote "origin"]
	url = https://Gorpeln@github.com/Gorpeln/postDemo.git
	url = https://gorpeln@git.dev.tencent.com/gorpeln/postDemo.git     #添加新地址
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master

地址是配好了，但是还要注意分支一致。我这里都用master，就不会有问题。

2、更新多个不同名字的远程仓库

添加一个名为“coding”的远程仓库：

git remote add coding https://gorpeln@git.dev.tencent.com/gorpeln/postDemo.git

执行完这条命令后.git/config文件内容变成了：(你也可以直接修改)

[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
	ignorecase = true
	precomposeunicode = true
[remote "origin"]
	url = https://Gorpeln@github.com/Gorpeln/postDemo.git
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master
[remote "coding"]
	url = https://gorpeln@git.dev.tencent.com/gorpeln/postDemo.git 
	fetch = +refs/heads/*:refs/remotes/coding/*

此时已经是一个本地仓库，两个远程仓库。使用下面的命令可以分别从两个远程仓库拉取和推送到两个远程仓库。

git pull origin master
git pull coding master
git push origin master
git push coding master
