comment Are multiple redirects within an AND-OR list valid in POSIX shell syntax?
Thanks! That was a serious mistake in my question. I have fixed my question and worked the whole thing out once again and it indeed seems like a valid if_clause but I would like someone to check my derivation and confirm if it is correct.

Are these man pages from the POSIX standard? Could you please share the URLs to these documents? Could you also please answer the three specific questions I have asked?
