-Raspbian Jesse changed the way a static IP Address is configured. The static IP settings are now held in a file located in the //**/etc**// directory called //**dhcpcd.conf**//
+Unlike Windows, Linux does not have files that are executable, all files can have this attribute. So for example, I have a python file that is just a text file, and I will to be able to run this from the command line, If I look at the file using ls -al:
 \\
-To edit the dhcpcd.conf file, enter:
+    ls -al
 \\
-        sudo /etc/dhcpcd.conf
+I will see something like this:
 \\
-At the end of the file add the following lines (with your own IP Address values)
+    "-rw-r--r-- 1 pi pi 4452 Jul 25 17:46 40x2_LCD.py"
+\\
+The permissions for this file are:
 \\
+    "-rw-r--r--"
 \\
-    eth0
+This file has three sets of permissions:
+\\
+    User -rw  |  Group -r-  |  Others r--
+    where r is read - w is write - x is execute
+\\
+\\
+I will cover permissions in another section, to give this file 'everything' use the following:
+\\
+    chmod 777 40x2_LCD.ph
+\\
+If we look at the permissions now by using:
+\\
+    ls -al
+\\
+We will see:
+\\
+    "-rwxrwxrwx"
+\\
+Now we can execute this file (assuming it contains something valid that is executable)
+\\
+    ./40x2_LCD.ph
+\\
+The file will now be executed.
