I want to insert a new line of text at a certain position in certain files

I've done stuff like this before with the rpl script and it works well as

I finally hit the point where I'm forced to learn something like sed or
awk and tried some examples with sed but I can't figure out what I'm doing

I get results like this:

sed '5i\test' test.txt
sed: 1: "5i\test": extra characters after \ at the end of i command

You want:

sed -e '5i\
test' test.txt

i.e. a linebreak after the backslash.

I had actually tried that too:

> sed -e '5i\
? test' text.txt
sed: 1: "5i
": command i expects \ followed by text
