Just a quick update, you should be able to just point to it in terminal then run the script.

so cd to script, /home/user/MyDocs/
then run one of the following
sh n900sync_generic.sh
or bash n900sync_generic.sh
or ./n900sync_generic.sh

If you still can't get it working I will check back maybe tmrw.

Cheers
