Hi Izak,

you may have a look here:

    How to use GRASS in batch mode (fully script based)?:

This has been simplified in GRASS 5:

grass5 -help
Usage:
    grass5 [-h | -help | --help] [-text | -tcltk] [[[<GISDBASE>/]<LOCATION_NAME>/]<MAPSET>]

Flags:
    -h or -help or --help          print this help message
    -text                          use text based interface
    -tcltk                         use Tcl/Tk based graphical interface

Parameters:
    GISDBASE                       initial database
    LOCATION_NAME                  initial location
    MAPSET                         initial mapset

    GISDBASE/LOCATION_NAME/MAPSET  fully qualified initial LOCATION directory

Environment variables:
    GRASS_TCLSH                    set tclsh shell name to override 'tclsh'
    GRASS_WISH                     set wish shell name to override 'wish'


Hope this helps,
