shell script help needed

Hi, I'm using Trinity 3.5.13.2 that was installed with exe GNU linux.

I have a bash script to mount a shared folder from a remote server and open it in a window. I launch it from a desktop icon. It looks like this:

sudo mount 192.168.0.2:/home/dpjungk/Share /mnt/nfs/client1 nautilus /mnt/nfs/client1

It works fine -- except that, if I close the window and want to reopen it, it obviously asks for the password every time.

Is there a way to check to see if it is mounted so that it only asks for the password if it is the first time?

Thank you for your time,

Don
