- I can't tell if you're asking about the specifics of some (made up) shell that only exists in that puzzle, or about how those variable and parameter work in actual mainstream shells. If the former, there's probably no way for us to know; if the second, it doesn't answer anything about how the made up shell in the puzzle behaves...ilkkachu– ilkkachu2021-09-16 19:44:15 +00:00Commented Sep 16, 2021 at 19:44

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
