Which rules (if any) make this answer:
Invalid, or, at least, wrong ?
Just shocked to get 3 downvotes so quickly for a perfectly correct (IMO) answer. If anything is wrong, please show me what !!! Thanks if you do.
But maybe, just maybe, this is just an example of this site (very) biased reaction.
The comments (which will probably be erased) say:
- The answer is not incorrect
well, since you ask, this answer seems like it pretty much only copies solutions from earlier answers, without attribution, at worst identically and at best with minimal changes. Now, I'm not sure if doing that's forbidden as such, but at least it doesn't seem too useful. That might explain some of the downvotes. (Or it might not, it's hard to tell what people think.) – ilkkachu
If the answer only copy other answers, and those answer were upvoted, the copies are valid answers, not wrong.
- There were new solutions included:
The xxd solution (the main reason to post) is mentioned nowhere else. For the ordering I decided to use that went to the middle of the list. Hmmm: the alternative with \u is also new and finding for which versions of the shell each solution works demands research. Is that also "a copy". I disagree.
The selected answer started with just one simple command
echo $'\x40'. If just one solution makes an answer valid, mine, which added at least two new solutions should make the answer valid.
- But the problem is not with the validity of what was said, or with any mistake. It is just the result of a subjective value judgement.
no, I don't like answers that don't bring anything new. I won't say the P-word, but it did come to mind. Don't mince my words, there's enough reason in what I actually said. (Someone else seems to agree too.) The one with '\u40' goes into the "minimal changes" category, and doesn't seem to have any upsides compared to \100. The xxd one wasn't there before, I'll give you that. Not that I see any upsides to that one either. But the first, fourth, and seventh ones, plus man ascii are pretty much literally from earlier answers, so that's what, half of this answer? – ilkkachu
In short: I don't like
That pretty much proves the point:
this site shows (very) biased reactions
