Git

Ref: Git 多用户配置

Unset global configuration:

git config --global --unset user.name
git config --global --unset user.email

Check:

git config --global --list

1. Use ssh key for git authentication

Generate key file:

ssh-keygen -t rsa -C "colin@gmail.com" # -C: comment to identify the key

Add public key to GitHub ,GitLab, or etc.

Add private key to localhost:

ssh-add ~/.ssh/id_rsa_github

Let's check:

ssh-add -l

2. Multiple git user:

Edit ~/.ssh/config:

Host github
HostName github.com
User jitwxs
IdentityFile ~/.ssh/id_rsa_github

Host gitlab
HostName gitlab.mygitlab.com
User lemon
IdentityFile ~/.ssh/id_rsa_gitlab

Test:

ssh -T git@github.com
ssh -T git@gitlab.mygitlab.com

3. Set commit user name for repo

git config --local user.name "name"
git config --local user.email "colin@gmail.com"

Check:

git config --local --list
