The goal of this document is to collect instructions for performing unattended / silent installations of many popular application installers. Such instructions are useful for automating these installations. A quick word on terminology: Strictly speaking, an unattended installation is one which does not require user interaction, and a silent (or quiet) installation is one which does not display any indication of its progress. However, most people use these terms interchangeably. Here, we are interested not only in performing unattended installations, but also in waiting for those installations to finish and suppressing any reboot they might want to perform. This is necessary for reliably installing multiple applications.
