body: <p>How to make a programme executable in the SHELL</p>
  
  <p>I have git cloned a number of tools into my HOME folder. Now as there are many of them and my query files are located on a different directory, what I need is make a programme executable from everywhere in the SHELL. I have read <a href="https://unix.stackexchange.com/questions/3809/how-can-i-make-a-program-executable-from-everywhere">this thread</a> but how about Perl and Python scipts. For example, I have a script.pl or script.py file in a folder named scrips. What should I do to make that script run from everywhere?</p>
