This question already has an answer here:
I have a different git repository for my office and a different git repo for my hobby projects.
When I do git config --global user.name
the user name changes globally and this creates a confusion
of committing to a repo with user name.
Hence the question is how can i have the same username across all my hobby projects and the same username across the office projects. I use the same machine to work on both the places.
Just use --local instead of --global. In fact, local is the default so you can just do
git config user.email personal@example.org
git config user.name "whatf hobbyist"
in one repo, and
git config user.email work@example.com
git config user.name "whatf at work"
in another repo
The values will then be stored in in the .git/config for that repo rather than your global configuration file.
Omit the --global from your call to git config:
git config user.name "A. U. Thor"
This will set the property in the current repository.
