Commit and push to multiple Git accounts on the same computer?

I use GitHub for my personal projects.

I love GitHub.

My portfolio, my Spring Boot project, my Django project… Any personal practice is on my GitHub. (Here.😉)

However, I use GitLab at work.

And sometimes I want to practice some tools and technologies that I need to learn at work but want to commit and push on my personal (GitHub) account on my work laptop!!

How can I manage and use multiple git accounts on the same computer?

Here is what I’ve done and leave this a quick note to myself.

Today’s goal!

Again, here is what I wanted to do:

• Main git account: GitLab (work)
• Sub git account: GitHub (Personal)

And my file directory structure is like this;

1. Setup my main git account

— Use git config global.

I think this is already set up when you build your local environment.

This will be your main git account, so set it globally.

$ git config --global user.name "<main account username>"
$ git config --global user.email "<main account email>"

To check if it’s applied, you run;

$ cat ~/.gitconfig
[user]
    email = <main account email>
    name = <main account username>

2. Setup my sub git account

— Use git config local, set each repository.

To set up your personal git account, you need to set it by a repository.

And set those configs in <repository>/git/config .

First, clone your personal repo and move to the repo.

$ cd practice/personal_project
$ git config --local user.name "<sub account username>" 
$ git config --local user.email "<sub account email>"

To check if it’s applied, you run;

$ cat .git/config                               
[core]
  repositoryformatversion = 0
  filemode = true
  bare = false
  logallrefupdates = true
  ignorecase = true
  precomposeunicode = true
[remote "origin"]
  url = https://github.com/yuki-nagano/personal_project.git
  fetch = +refs/heads/*:refs/remotes/origin/*
[branch "main"]
  remote = origin
  merge = refs/heads/main
[user]
  name = <sub account email>
  email = <sub account email>

You’re all set!

Now you can commit and push with your main/sub account separatedly!
