it also tests linking a tmpfile...

You could just replace the  check for the $testfile existing and
then the removal with:

rm $testfile

because if it doesn't exist that will thrown an ENOENT error like:

rm: cannot remove "foo": No such file or directory

And that will fail the test. There's also no reason to exit if there
is an error, because the rest of the test does not depend on
$testfile being removed. The golden output comparison will then
cause the test to fail...

Cheers,

Dave.
