Once installed, run "adb" and "fastboot" in a terminal to see the available options and how to use these Android tools.
Update 1: we've now backported the Ubuntu Raring builds to Ubuntu 12.10 as well as Ubuntu 12.04 and 11.10. This includes a new android-tools-ext4-utils package (“sudo apt-get install android-tools-fsutils”) and udev rules to allow fastboot flashing Nexus7.
Update 2: The "android-tools-adb" package now includes / installs 51-android.rules Udev rules. This isn't available in the official Ubuntu package but only in the package available in our PPA, and is available for Ubuntu Raring, Quantal, Precise and Oneiric.
