thanks to all four of you who replied and solved this problem to a
large extent, building on each other's ideas.

I would have done it by the first method of concatenating or pipes
into a sed which replaced end by the next and # can be placed after
pipes. the string then fed into a bash.

Stefan, whats the purpose of the colon ? it works without colon also.
Is it subshell or some environment import ? like the colon which can
substitute the #!/bin/bash on the top ?
