   "description": "clone a sandbox org\nThere are two ways to clone a sandbox: either specify a sandbox definition file or provide key=value pairs at the command line. Key-value pairs at the command-line override their equivalent sandbox definition file values. In either case, you must specify both the \"sandboxName\" and \"sourceSandbox\" options. Set the --targetusername (-u) parameter to a production org with sandbox licenses. The --type (-t) parameter is required and must be set to \"sandbox\".",
