I agree that too many questions
that are posted on a site where they are on-topic
get erroneously migrated to Stack Overflow.
This is a bigger problem on Unix & Linux Stack Exchange,
where some people react to anything that looks like source code
the way people in warm climes react to a snowflake,
but I guess it’s a problem here on Super User, too.
While I tentatively agree that
is on-topic at Super User,
I believe (as a very low-involvement member)
that it is on-topic at Stack Overflow also:“software tools commonly used by programmers”
are explicitly listed as being on-topic there.
In any case, Stack Overflow seems to be happy to accept questions
that belong on Super User or U & L,
such as how to run commands from the command line,
on the (IMHO flimsy) rationale that
anything that could be used on the command line could be used in a script,
and therefore it’s programming-related.
(Similar rationale for Excel worksheet formula questions, I suppose.)
