I have a task that will benefit from writing a good question on Stack Exchange - in that I think the results will be instructive in general. Of course.
Clearly, this is a case where there are many degrees of freedom, shall we say. I am balking at writing a question (I'm thinking Code Review, Stack Overflow, Unix & Linux, and maybe Super User) with this dilemma:
write a specific, narrow question about awk, fields, wildcards, etc. It will look "academic" with
echo aa.aa,bb.bb,cc.cc,dd.dd | awk [..and so on..]and so on as can already be found on Stack Overflow - and are, IMHO, instructive.
... so guidance how to write such a question, or where to post perhaps individual "academic"-ish questions will help me write a better question.
**from doing more homework:
it appears that indicating the JSON file format is important now. originally thought it wasn't a biggie because I start with SVG, which I say.
Homework repeatedly led me to few posts on Stack Overflow (I tend to go to S.O. and U.& L.) that assert sed or awk is not "designed" to parse JSON data and will be "fragile (at best)".. I note the answer with that assertion has +8.
