title: Make executable file run without prompt in linux
body: <p>Every time I ran an executable installed in the system it's all fine without any prompt, but recently I configured my <code>vim</code> editor to do <code>c++</code> coding. Every time I build a program using make through <code>vim</code> and want to run the built executable, a pop up shows that this file is an executable and whether I want to execute it??</p>
  
  <p>How do I turn that thing off so that no prompt will annoy me?</p>
  
  <p>edit:
  The prompt appears only when double clicking the file outside the vim editor.
  using LXDE desktop on debian.</p>
  
  <p>edit:
  I noticed that any executable file double clicked in file manager gets the same pop up.
  when launching the app through the desktop panel it is fine.</p>
