I have a file that i want to take a block chunk out of it, but only the first occurance of the patterns. example of file below: I want to use sed to capture everything from aaaa to first prod. I tried something like /aaaa/,/prod/p but it gave me the first and last pattern match. I just need the first. If it's not to much to ask is there also a way to use the same patterns and get it to capture the second aaaa to prod while skipping the first. I'm going to be adding the sed command to a ksh script. Thank you.

aaaa
....
....
....
prod

bbbb

prod

aaaa
