And mawk is (was in 16.04 at least) the default version of awk on Ubuntu. How is the user supposed to know this magic incantation? ¯\_(ツ)_/¯
- mananaysiempre 5y agoTo be fair, I can see this coming out of a strict reading of POSIX: it doesn’t say a single word about GNU-style long options (though there is an implied hole where they can fit), but explicitly leaves -W with an argument as a place for implementation-defined crufties when passed to Awk (I haven’t the slightest idea why). (Honestly I’d rather not have the convention of programs themselves handling this at all and instead have this be `ident awk` or similar, but I understand this is not going to happen.)
- saghm 5y agoI can only imagine that the "w" stands for "what the hell do I need to pass this thing to get it to tell me something useful"
