How to pass variable's values in multiline string shellscript

Question

I have a variable called instdir that has the current directory. I need to pass its value to a multiline string that will be written to a file. As instdir finishes with a slash I can't do anything like this:

cat > test <<EOF
  $instdir/final/path/to/file
EOF

But If I use $instdirfinal instead, it won't recognize the real instdir's value. What I suppose to do?

Answer 1

Here's the trick:

${instdir}final
