+===== Manipulating the PATH variable =====
+Your shell will allow you manipulate the order in which these paths appear. It's as simple as setting a variable.
+For the following examples I assume you are using the bash shell, which is the default in CS. The concept will translate to other shells, though the syntax may be different.
+A common example to manipulate your path is if you have written a script and you'd like to invoke it without providing the full path:
+Lets create the directory ''%%bin%%'' in the root of our home directory:
+<code>
+user@linux1:~$ mkdir ~/bin
+</code>
+We will place our example script that echo's 'Hello World!' into ''%%~/bin/hello%%'' and make it executable.
+<code>
+#!/bin/bash
+echo 'Hello World!'
+</code>
+<code>
+chmod +x ~/bin/hello
+</code>
