What is the salesforce CLI?

Hi @Shana Hawtrey

The Salesforce CLI is a powerful command line interface that simplifies development and build automation when working with your Salesforce org.

Use it to:

• Aggregate all the tools you need to develop with and perform commands against your Salesforce org
• Synchronize source to and from scratch orgs
• Create and manage orgs
• Import and export data
• Create and execute tests
• Create and install packages
