+If you followed the previous link:./prerequisites.adoc[prerequisites] tutorial and create a new identify file name `qdup` then we need to tell qDup to use that instead of the default identify file.

 == Changing the greeting
 
 The `- sh: echo ${{message}}` command uses pattern substitution. qDup uses the `states` value for `message` but we can change that when running qDup by passing in a different value for `message` through the command line.

 The `-S` argument overrides the value in yaml. We can store a default in yaml then use the command line to customize the script execution.
