I’ve been a freelancer for quite some time, and for approximately the same amount of time, I’ve been making the same mistake, over and over, again. Whenever I had to work for multiple customers in the same period of time, I would always mix-up the email addresses in my Git configuration, and end up committing code on a client’s codebase and sign it with the email and details from another client.

And it was all because of the two commands below:

$ git config --global user.name "Adrian Oprea"
$ git config --global user.email "company@email.com"

Whenever I looked for help on how to set my name/email configuration in Git, I found these two commands. It doesn’t matter which Git provider you’re using, GitHub or GitLab, it’s all the same. So I did what everyone would do, I copied and pasted those commands over and over again.

There’s nothing wrong with setting a global name/email in your git configuration, I have them set up for my public/open-source projects, but for your client projects, use the local config. This way, you’ll have project-specific configuration, at the project level, and shared settings at the global level.

So instead of using the --global flag, just use the --local flag, and everything will be set at the repository level, in the local config file — .git/config.

In order to configure my details on a repository basis, all you to do is to paste the following lines, in the command line:

$ git config --local user.name "Adrian Oprea"
$ git config --local user.email "company@email.com"

This means that you can keep your global settings intact and only update the configuration at the local level.

Bonus

To view all the values that are currently set at the local/global level run one of the following commands in your terminal emulator of choice:

$ git config --local --list
$ git config --global --list
