it fails to delete the address space, and the footer remains in the
message. Can anyone see what my problem is?
Each of the regular expressions that specify an address range can have
its own modifier. You're only asking for a case-insensitive match on
the end of the address range, but not on the beginning. Compare:
# echo -e "One\nTwo\nThree\nFour" | sed "/two/,/three/d"
One
Two
Three
Four
# echo -e "One\nTwo\nThree\nFour" | sed "/two/I,/three/d"
One
# echo -e "One\nTwo\nThree\nFour" | sed "/two/I,/three/Id"
One
Four
Add another "I" before the comma in your last line to make both
regexes case-insensitive.
