func:tldr:eacc5

This command is used to fetch the application settings of an Azure Function App.

Here is the breakdown of the command:

• func: This is the Azure Functions Core Tools CLI (Command Line Interface). It provides a set of commands to interact with Azure Functions.
• azure: This is a sub-command of the func command, specifically used for executing operations related to Azure resources.
• functionapp: This is another sub-command of the func command, used for managing Azure Function Apps.
• fetch-app-settings: This is a command option that instructs the CLI to fetch the application settings of the specified Function App.
• ${function}: This is a placeholder that should be replaced with the name of the Function App for which you want to fetch the application settings.

When you run this command with a valid Function App name, it will fetch and display the application settings of that Function App. Application settings often include configurations like connection strings, environment variables, or other settings required by the Function App to run correctly.
