+<color red>NOTE:- </color>While this works fine for scripts run from the command line, I found anything run by CRON failed if this format was used (this was on Raspbian Jessie).

+When you want to redirect the output of a command to a file you can use the redirector **>**
+\\
+    ls -al > result.log
+\\
+However, this means that you see nothing on the screen, to avoid this use the **Tee** Command:
+\\
+    ls -al | tee result.log
+\\
+Now you get the result on both the screen and in the file.
