Which will fail if "$script" contains whitespace, and cat is
unnecessary:
content=$( sed '/function codecs/,/fi;/d' "$script")

If you don't quote $content, echo will put it all on one line.
content=$(echo "$content" | sed -n '/mandriva/,/fi;}/p');
content=$(echo "$content" | sed '/^\s*urpmi[:space:]--auto/p');
