bash - how to insert ctrl+d into my linux script?

I want to make the following commands:

cat > template.txt [enter in the terminal] text [Ctrl+d in the terminal]

in a script.

Is there a way to tell the script to do enterCtrl d? Is there a way to create a file and write to it in script?

I didn't find anything that worked for me.

Thanks.

A Here Document is kind of like a script version of what you're talking about, I think, although it is not entirely clear to me from your description.

#!/bin/bash

cat > template.txt <<- EOF
    Here
    is some 
    text.
EOF

Ctrl-D itself is the EOF character, ASCII 4.
