Yes, you are right. I just tested this and it works fine. However, what is
happening here is probably that your editor adds a new line so what the server
really sends is "OK\n" which causes the test to not trigger as the regex does
not match just "OK". If you remove the new line char '\n' it works fine. It
seems that something is fishy with $ in a POSIX regex, at least on my machine.
In my book ^OK$ should match "OK\n" but apparently it does not. An alternative
to write "OK" with no text behind and that works is to use '^OK[:space:]*'.
Otherwise, just make sure that the new-line char is not included in the
response from the server.
