Options for running - Executable text files

I have created some text executable files and put them on my desktop.
In the way of background I created them in gedit. Then used chmod ugo+x (filename) to make them executable.
One of them is a ping test to see if a printer is on. Text in file = ping
Others are to turn my laptop touchpad on and off. text in file = sudo modprobe -i psmouse

I have 2 questions about executable text files
First question
When I click on an executable text file it present a window with 4 options (Run in terminal, display, cancel, run).
Can I set a parameter or do something else so it just runs in terminal?
I know I can set an option in Nautilus to run them but when I select run nothing seems to happen. In addition I would want to set this option on a case by case basis not globally in Nautilus.
If there is an option or flag where it would run this file in terminal I would use it on my printer ping test.

Second question
When I click on these executable text files to turn my touchpad on and off, the text within the file uses the sudo command so that requires that I input my password. After I click on either of these files a window appears with the 4 options (Run in terminal, display, cancel, run). I select run in terminal, a terminal window opens and requests my password. Subsequent to inputting my password the file executes fine.
Is there a way to set a parameter or do something else so I don't need to not only select the run in terminal option from (run in terminal, display, cancel, run) but also not to enter my password?

Thanks in advance for your assistance.

Why not use the command line anyway ? If you insist on clicking things, create launchers for the scripts on your panel, and there is a setting to make them open in a terminal. It is not advisable to store the root password anywhere so automatic password entry is not a good idea.

Don't store the script itself on your desktop. Also, don't include sudo inside the script itself. Do this:

$ sudo touch /usr/local/bin/toggle-touchpad
$ sudo chmod u=rwx,g=rx,o=r /usr/local/bin/toggle-touchpad
Edit the file to look like this:

modprobe -i psmouse
Then add a line to /etc/sudoers:
username ALL=(ALL) NOPASSWD: /usr/local/bin/toggle-touchpad
Or instead, do it on a group basis:
%groupname ALL=(ALL) NOPASSWD: /usr/local/bin/toggle-touchpad
Finally, create a launcher on your desktop to run the command:
sudo /usr/local/bin/toggle-touchpad

This may be a duplicate thanks. I went away for a minute and didn't see my reply so thank you for taking the time to write such a detailed solution.
As I mentioned in my first reply I'm learning all the time.
I looked up the touch command you used and I will use it in the future to create empty files; very useful.
I also like the idea of listing the file in sudoers so I don't need to use a password. Once again very useful.
Also I never used launcher before so that was another great find.
I may bug you from time to time if I get stuck again - hope you don't mind.
Thanks again for the support.
