Help setting up a Regex string for CI routing

[eluser]stormbytes[/eluser]
Okay, so I'm not a Regex guru

I'd like a routing string that does the following:

Code:

routes['media/string' = 'media/index/$1';

where 'string' conforms to any letter/number/hyphen/underscore
combination EXCEPT one that ends in '/'

The idea is that ANY string following 'media' should be taken as an argument unless there's a slash at the end, which would mean that the string is actually a valid controller/method name.

I'd specifically like to route all requests to 'media/whatever without a slash at the end, to media/index -

thanks all your Regex Yodas out there
