git push -u <remote> <branchname>
Push commits to a remote repository
This command pushes the commits in the current branch to the specified remote repository. The -u flag sets the upstream branch for the current branch, tracking it for future git pull commands. The <remote> parameter specifies the remote repository to push to, and the <branchname> parameter specifies the branch to push.
Optionally, you can use the --set-upstream flag as a long version of -u.
Specific examples:
git push -u origin main
