I'm trying to execute something like this:

wget --user=foo --password=bar! url

The ! in the password is causing problems. I've tried escaping it with \, as in

--password=bar\!

I've tried encapsulating in single and double quotes. I put the password in a separate file and tried

--password=cat pass.txt

Each time, I get a 403 Forbidden. Using -d, I see that the SSL handshake is successful. On the Windows command line, the command works. My assumption is that I need to escape the ! differently, but I don't know how else.
