thank you for your answer
i have a question about [[ -v $next ]] i havent tried but you say it works
it would ? expand $next but wont it then check '[[ -v <content_of_next> ]]'
and fail ?
Try it. -v will evaluate an array reference with a subscript to see if that
particular element exists, but the general nameref resolution code does not
(and should not) re-evaluate an array expansion.
ill benchmark the usage of : $next ; before [[ -v now, if its minimal its
all fine i can use
i just remember it used to work
I doubt it, but it doesn't matter now.
for the [[ -v arr[++elem] ]] style i do cause i can add in the loop to the
array and it continues over the new elements, till no more
Come on, so does iterating from 0 to ${#arr[@]}.
i also have another this-same-declare issue with a more complex data structure
I think help-bash would be a good place for that discussion.
