The following sections will discuss each of these commands in turn, and discuss how to use them with Home Library FTPClient.
Configuration File
Home Library CLI is equipped with a simple configuration file to set the parameters and initial settings.
The fields are:
- URL_REPOSITORY: the URL of Home Library WebApp.
- USERNAME: username to connect to Home Library WebApp.
- PASSWORD: password to connect to Home Library WebApp.
