+If you want to automate these procedures it can be done by configuring apt's Periodic options. The Raspberry Pi comes with apt installed (it provides the apt-get commands, etc.), and as part of that package an automated script is installed (in /etc/cron.daily/apt) for doing automated updates on a daily basis (using the cron daemon). These may be controlled by creating (as root) a file /etc/apt/apt.conf.d/10periodic putting the following into it:
+\\
+<file>
+APT::Periodic::Update-Package-Lists "1";
+APT::Periodic::Download-Upgradeable-Packages "0";
+APT::Periodic::AutocleanInterval "0";
+APT::Periodic::Unattended-Upgrade "0";
+</file>
+\\
+This configuration will just run update every day for you so when you run sudo apt-get upgrade you'll install the latest packages (without having to first run apt-get update).
+\\
+\\
+===== Automatic Upgrades =====
+\\
+To configure apt to automatically upgrade packages as well - firstly you'll need to install a new package to make the unattended upgrades work:
+<file>
+sudo apt-get install unattended-upgrades
+</file>
+Then you change the following option to "1" in /etc/apt/apt.conf.d/10periodic to enable automated upgrades:
+<file>
+APT::Periodic::Unattended-Upgrade "1";
+</file>
+For more details see the comments inside the /etc/cron.daily/apt and then put the relevant options into the /etc/apt/apt.conf.d/10periodic file.
