Good to hear.
Thanks for letting us know.

The sed line is identical in operation to the awk one:
(1). Delete anything that's not in the range of lines from /foo/ to /bar/;
(2). Print the lines that match the range specified;
(3). Quit processing further lines of input on finding the first
occurrence of /bar/;
