How to push changes from local git repo to GitHub with Finegrained Personal Access Token (PAT)

Make sure your .env file is loaded in the shell:

export $(grep -v '^#' .env | xargs)

This sets GH_TOKEN as an environment variable.

Configure Git to use the token for HTTPS:

git remote set-url origin https://github.com/<username>/<repo-name>.git

Push using the token without embedding it in the URL:

git -c http.extraheader="AUTHORIZATION: bearer $GH_TOKEN" push origin main

-c http.extraheader="AUTHORIZATION: bearer $GH_TOKEN" tells Git to use the token for authentication just for this command. This way your token is never saved in Git config or remote URLs.
