$(release) is wrong. That will execute a command named release. You need ${release} instead. Or actually you can use it without any kind of paren/bracket as it was explained.

And again, do not forget to use shellcheck, that will help you to write correct and working code.

No, it's not wrong in this case. Just a peculiarity of Azure Pipelines. That one is a macro syntax variable, not a regular shell variable. See Define variables and Set variables in scripts in Azure Pipelines docs.

So it is not linux bash as it was written in post #16 ( ... I use only linux bash ...).
But an embedded bash script in a yaml file. Nice. In that case "$(release)" is the correct syntax, as it was already posted in #11.
