I have a question about this recent AU question. My answer (let's call it A2) was not accepted, in favour of another one (A1). I don't mind this that much, but I would like to understand if the situation is all kosher, and if there is anything I can do differently in the future. Here are some facts:
My answer A2 was first by more than 3 minutes.
In the original form (rev 1), A2 succinctly answers the OP (IMO). The 2 subsequent revisions only add some extra information.
The answer A1 contains false information in revs 1&2 (about the ordering of the output). I made a comment about this issue, which was subsequently incorporated in A1 rev 3.
A1 rev 4 copies a part of A2, that addresses the printing of the last word, which was a small part of OP.
A1 rev 5 copies from A2 the clean-looking example code
tee >(wc -l) >(wc -w) >(wc -c).
Are there any rules that might apply to this situation? For example, does the timing (being first) and content of A2 rev 1 matter at all? Is this all at the OP author's discretion? Also, is it ok for A1 to appropriate parts of A2? Is there anything I should do differently in such a situation?
