Access two github accounts in one linux machine

Assume you already can access your person github repositories using public key id_rsa.pub

1. Create another ssh private / public key pair

   # file name: ~/.ssh/id_rsa2
    ssh-keygen

2. upload public key to your company's github
3. create a ssh config at .ssh/config

   Host github.com
     HostName github.com
     User git
     IdentityFile ~/.ssh/id_rsa
     AddKeysToAgent yes
     ServerAliveInterval 60
     ServerAliveCountMax 30
   
   # Work GitHub account
   Host github-work
     HostName github.com
     User git
     IdentityFile ~/.ssh/id_rsa2
     AddKeysToAgent yes
     ServerAliveInterval 60
     ServerAliveCountMax 30

4. clone work repository

   git clone git@github-work:mycompany/jackt.git

5. clone your person repository as normal because it will use the default ssh config
