Grass was a separate program from QGIS for a long time (it still is). We will only be using the plugin for this course, but the following sections provide some information on acquiring it as a separate package.
GrassGIS is available as a binary package for the majority of UNIX/Linux systems, for Windows OS and for MacOS. For some systems, you will need to install the GrassGIS using source code. The part ( ) illustrates how to install GrassGIS v.6 on UBUNTU Linux.
