+===== Change the default shell to bash =====
+By default, Ubuntu has Dash as the default shell.
+  * Bash is preferred.
+  * The reason that dash was set as the default is that dash provides faster boot times.
+  * It does not however have the full feature set offered by bash.
+  * On a modern server this speed difference in booting is negligible; and not too important as servers usually are not booted very often.

-===== Install multimedia codecs =====
+===== Update inputrc =====
+Update **/etc/inputrc** to support being able to use arrow keys for history searches.
+Add the following lines to the bottom of the file.
+<file bash /etc/inputrc>
+...
+# Peter added these
+"\e0A": history-search-backward
+"\e0B": history-search-forward
+"\e0C": forward-char
+"\e0D": backward-char
+"\e[A": history-search-backward
+"\e[B": history-search-forward
+"\e[C": forward-char
+"\e[D": backward-char
+</file>
+<WRAP info>
+**NOTE:**  This allows one to type the first letter of a previous command, and then by using the arrow up key for example, will only show previous commands also starting with that letter.
