Kellyn Pot’vin-Gorman shows how easy it can be to write Bash scripts with variables:
Let’s start with a use case of deploying a Azure database. When a customer is making the decision to build it out, there are specific information needed to deploy and this will continue to change as the Azure catalog is updated with new offerings. For our example, we’ll stick to a very small snippet of code, as the values we dynamically create will be reused throughout the script. This example will skip past the actual server creation, etc. and just focus on the user database creation. The Server, zone and subscription are all set in the default steps earlier on so as not to have to repeat it throughout each resource deployment step.
There’s a lot to Bash and its programming guide is a lot of sheets of paper (ask me how I know), but this is one of those places where you can get a nice benefit easily.
