Git multiple users

1. Different user email/name for different remote

Matching the specific domain

sh
vim ~/.gitconfig
ini
[user]
	name = yunyuyuan
	email = me@yunyuyuan.net

[includeIf "hasconfig:remote.*.url:git@git.example.com:*/**"]
    path = .gitconfig-another

Add a configuration

sh
vim ~/.gitconfig-another
ini
[user]
	name = another-user
	email = another@yunyuyuan.net

2. Different identity for specific user

Generate a new identity

sh
ssh-keygen -f ~/.ssh/id_rsa_another

Config the magic Host

sh
vim ~/.ssh/config
ini
# default user
Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa

Host github.com-another
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_another

Then use this to git clone:

sh
git clone git@github.com:default_user/xxx.git
git clone git@github.com-another:another_user/xxx.git

3. Custom SSH port

sh
vim ~/.ssh/config
ini
Host git.example.com
  HostName git.example.com
  User git
  Port 222
