In general, when I need to iterate over a set (in bash), I use "mapfile".

I think more or less the same is available in ksh.

Not that I'd know of. - Maybe getting something similar using some
standard mechanisms? - If I understand 'mapfile' correctly it may
(basically) do something like   IFS=$'\n' arr=( $( ... ) )    ?

 
Oh, and another thing of interest to the original thread.  We were talking
about whether the real underlying problem in the "rm" command could or
should be fixed.  I did some reading and some testing.  "man rm" (on Linux)
does mention stdin being a terminal - implying, somewhat obliquely, that
the -i option checks that and behaves differently if stdin is not a
terminal.

In case stdin is not a terminal I'd not expect the flushing of the
prompts; in case that condition is even checked I'd rather expect
a warning message. (But I haven't thought about that to any depth.)
