The command "heroku ps --app ${app_name}" is a command used in the command-line interface (CLI) tool for Heroku, a cloud platform that allows developers to deploy, manage, and scale applications.

Here's an explanation of each part of the command:

• "heroku" is the CLI tool's name, and it is used to interact with the Heroku platform through the command line.
• "ps" stands for processes and is a command that lists all the dynos (instances of an application) running for a specific application on Heroku.
• "--app" is an option used to specify the Heroku application for which you want to view the processes.
• "${app_name}" is a placeholder for the actual name of the Heroku application. It should be replaced with the correct name of your application.

When you run the command, it will display a list of all dynos and their corresponding states (such as running, idle, crashed, etc.) for the specified Heroku application. This information is helpful for monitoring and managing the processes running in your application on the Heroku platform.
