There are tools I'd consider using for this such as tcl/expect which
help with simulating interactive sessions and with coordinating
multiple actions. Forget the "sh only" approach if it makes things
difficult; some platforms ship with a much richer toolset, and these
tools might be well suited to your problem.

If it works and there is a big demand for the "sh tools" then someone
can recode it later, and it isn't holding you up now.

... my 2 cents...
