Create a config file in ~/.ssh/

vim config:

# PERSONAL ACCOUNT Github
Host github.com-COOL
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_COOL

# COMPANY GitHub

    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_COMPANY

Setting up different config settings for each project:

CD to a project folder:

git config user.name "Your Name Here"
git config user.email [email protected]

git config --global user.name "Your Name Here"
git config --global user.email [email protected]

git clone [email protected]:COMPANY/

git cline [email protected]:USERNAME
