What Others Think

You don't need to escape the second part; it's not a pattern. In fact, I don't think that'll produce the correct result.

@kaedenn Thank you very much! I had not thought about it.

Did you even try this? :) At least with my version you get a "Final $ should be \$ or $name at (eval 1) line 1, within string". The replacement shouldn't have any regexy stuff in it except backreferences -- the dot doesn't need escaping (as pointed out by kaedenn) and the dollar doesn't mean anything. So you want rename 's/\.txt$/.md/i' *
