How to run executable scripts in Nautilus?

when i am trying to open executable scripts (e.g. .sh) from nautilus then it will directly open scripts into text editor.


Solution:
1. open Nautilus
2. Open this from menu bar.
           settings -> Preferences
3. Select the 'Behavior' tab.
4. Select "Ask each time" under "Executable Text Files".
5. Close the window.



And it works.
