I have a line of code in using sed that extracts the frist instance of a word and extracts the entire segment of code associated with that word and writes it to a file. I don't want to extract the lines I want to delet them what am I missing? Here's what I have so far:

sed -e '/./{H;$!d;}' -e "x;/REGEX/!d;" FILENAME > OUT.TMP

Ideally I'd like to redirect the output to OUT.TMP while deleting it from FILNAME all together.

The output in OUT.TMP would look like this

To extract that part, I guess it's best to use
To delete it from the file, I think you'll have to invoke sed once again:
