It no longer being a valid shell (if on startup) or providing an invalid cd built-in (when cding), from the stand-point of conformance to both the standard and historical shells. > I would make it clear in the text that this > is a spec requirement, not a practical guarantee (e.g. "required by > <spec> to be ..."). Those are one and the same, that's the point of SUS/POSIX (and conformance to historical implementations). Are you aware of one or are you just concern-trolling? Obviously, pretty much no part of this manual applies to csh because csh is its own 2BSD brand of insanity (in this case largely because it predates V7 (3BSD), and, hence, the environment). csh users understand they use a non-shell, it's not mentioned here because why would it be? It's not mentioned anywhere else. Best, наб
