Hi Chris, next time you should be a little more polite. That could help a lot.
What you misunderstand here is that $ is not a character range, such as [a-z],
it is a zero-width assertion.
e.g: /a$[^x]b/m matches to a\nb, since $ itself just checks a condition, but
does not change the character position.
\r[^\n] this pattern matches to two character long strings. E.g, it matches to
\rx but not to \r or \r\n. Here, [^\n] is a character range, so it does not
match at the end of the input.
\r[^$] also requires two characters, the first one is \r, followed by anything
which is not $ (here, $ is a plain character), so it matches to \r\n, but not
to \r$.
I hope now everything is clear.
