Re: [Fab-user] List of files in directory

Hi,

Thanks for the answer. I think it would be fair to state that using bash 
commands aren't the most pythonic way of doing this.

I was thinking of writing a patch to add the wrapper functions, but would only 
do so if it would actually have a chance of being added to fabric. Would it 
have a chance?

Cheers,

Ps: fabric is awesome!
