What is the purpose of the command "sfdx copado:auth:set -a [myOrgAlias]"?

The command "sfdx copado:auth:set -a [myOrgAlias]" is specifically designed to link the Copado Command Line Interface (CLI) with a Salesforce org. When executing this command, you are establishing a connection between Copado and the specified org alias. This connection is crucial for allowing Copado to manage and deploy changes within that particular Salesforce environment.

By linking the CLI to the org, you enable various functionalities that Copado offers, such as managing metadata deployments, tracking changes, and executing CI/CD processes. The use of the org alias is essential as it tells the CLI which Salesforce org it should be interacting with, ensuring that all operations are directed to the correct environment.

The other options do not accurately reflect the purpose of this command. For instance, the command does not authorize a new user, create a new scratch org, or deploy a package, but rather focuses entirely on setting up the connection between Copado CLI and the chosen Salesforce org.
