     ls -l example.py
+    -rw-r-xr-- 1 pi pi 4452 Jul 25 18:01 example.py
+    The group rights have changed from ----r------ to ----r-x---  (only looking at group, not listed Owner or Other)
 \\

+If required, more than one permission can be changed at once, for example I want to give write and execute to 'Other'
