You're calling filter_ssh with no arguments, but trying to use "$@"
inside it to generate the ssh command.
You're also using dots inside a regex without backslashing them. And
I'm not sure about the parentheses -- can't tell whether you meant those
to be literal or not. They don't appear to serve any purpose if they're
not literal (there's no | inside them for example), but you didn't
backslash them either... very confusing.
Finally, using \w here is a libc extension and will only work on your
system, not necessarily other systems. Just FYI.
