#Clone repo
#

git clone git@github.com-work_user1:work_user1/repo_name.git


#
#For Locally Existing Repositories
#
If we have the repository already cloned:

List the Git remote of the repository, git remote -v

Check whether the URL matches our GitHub host to be used, or else update the remote origin URL.

git remote set-url origin git@github.com-worker_user1:worker_user1/repo_name.git
Ensure the string between @ and : matches the Host we have given in the SSH config.

#
#If you are creating a new repository on local:
#git init
Initialize Git in the project folder git init.

Create the new repository in the GitHub account and then add it as the Git remote to the local repository.

git remote add origin git@github.com-work_user1:work_user1/repo_name.git 
Ensure the string between @ and : matches the Host we have given in the SSH config.

Push the initial commit to the GitHub repository:

git add .
git commit -m "Initial commit"
git push -u origin master
