如何为不同git仓库配置不同的ssh key和user？

cd ${your repo dir}
git config user.name "FIRST_NAME LAST_NAME"
git config user.email "MY_NAME@example.com"
git config core.sshCommand "ssh -i ~/.ssh/id_rsa_xxx"

Sample

比如~/.ssh下生成了personal和company两个ssh key， 如何生成ssh key

ls ~/.ssh
id_rsa_my_personal
id_rsa_my_personal.pub
id_rsa_my_company
id_rsa_my_company.pub
...

为单个仓库指定ssh key

cd ${your repo dir}
git config core.sshCommand "ssh -i ~/.ssh/id_rsa_my_personal"

# Mac上再执行
ssh-add --apple-use-keychain ~/.ssh/id_rsa_my_personal

查看${your repo dir}/.git/config
