Configuring CLI Jenkins
Jenkins has a built-in command line interface that allows you to access Jenkins from a script or from your shell. This is convenient for automation of routine tasks, bulk updates, trouble diagnosis, and so on.
This interface is accessed via the Jenkins CLI client, which is a Java JAR file distributed with Jenkins.

- Setting Jenkins-cli as alias for running Jenkins-cli.jar
