GRASS Help System |
GRASS has often been referred to as a "tool chest" of commands. In this scenario, the user supplies the data and the notion of which functions to perform (i.e., a model), while GRASS supplies the commands (functions) necessary to run the model.
The GRASS commands listed below are actually UNIX shell scripts running a series of GRASS commands. They exist both to perform a specific function and to exhibit how such macros can be constructed. All (but r.average) are stored under the directory "$GISBASE/scripts". User sites are encouraged to examine these shell scripts and to develop their own macros based on these examples.
For more information on a specific command, select a command and press ESC.
