As you may see, i'm trying to write a simple nautilus script to upload folders recursively to my cellphone. However, the problem is in the boldface statements... echoing the command to a separate sh and then executing it / pasting everything into the terminal works perfect.
aashay@kriz:~/.gnome2/nautilus-scripts$ bash temp.sh
Connecting...done
Sending "E:"... Sending "Unsorted"... Sending "home"... Sending "aashay"... Sending "tempex"... done
Sending "/home/aashay/tempex/chrome-theme.so"...|done

But executing the exact same command through the script itself doesn't
aashay@kriz:~/.gnome2/nautilus-scripts$ ./send-to-phone2
File: /home/aashay/tempex/chrome-theme.so
Connecting...done
Sending "'E:"... failed: 'E:/Unsorted/home/aashay/tempex'
Sending "/home/aashay/tempex/chrome-theme.so"...\failed: /home/aashay/tempex/chrome-theme.so
