As a developer, when I switched from Windows & Ubuntu OS to Mac OS, I struggled a lot to discover the shortcuts. The shortcuts are not very obvious as in Windows or Ubuntu.

This blog post captures the command used to create and configure java apps or spring boot apps deployed to Heroku Cloud. I use these commands in CI/CD deployment steps for continuous delivery and also to access the application's information from my local development machine.
