Accessing my Droid Maxx from a shell script

[MR ZenWiz]

I pulled down the script found here:
http://askubuntu.com/questions/342319/where-are-mtp-mounted-devices-located-in-the-filesystem/342549

However, the top level directory is called "Internal storage" and I
haven't found a way to get the script to get through that directory.

I've tried quoting it, adding escape characters (2-4) and that space
just won't stop interfering.

Is there a way around this?

script to do it....

Thanks.
