Support For Variables In Snippets
Often times in scripts, there is dynamic content/strings/etc that need to be reused within a single script, or amongst different scripts. An example would be a URL that content needs to be downloaded from, e.g. it points to some binary content that will be downloaded to a device which has an SSH terminal connection for further processing (perhaps it's a firmware update, or other software). As it is now, that URL string would need to be changed in every script it's used in if that content location changes, or a new binary package is released and the URL changes. It's very cumbersome to change this content in numerous locations when you could just set up a named variable, like $URL which is a placeholder for the actual URL. This feature would save us a ton of time.
