I did a few commits to Github but the username and email were not the same as mentioned in github. Due to it wont show up in the streak graph in Github.
Solution here https://stackoverflow.com/questions/8801729/is-it-possible-to-have-different-git-configuration-for-different-projects
Once you clone a repo, run
git config user.name git config user.email
If you see the expected results, then continue with the development else you need to set the right values at repo level
git config user.name="" git config user.email="
to set it globally use --global flag.
You can use aliases to avoid manually typing the command but adding the below lines to global gitignore. Once you checkout the repo, run git and you can verify git config user.name
[alias]
dh-email = config user.email \"pes***@gmail.com\"
dh-name = config user.name \"dhbalaji\"
