DESCRIPTION
This program allows user to start a selected graphical user interface (GUI)
from the command line prompt.
Currently three different GUIs are supported:
- tcltk - Current Tcl/Tk based GUI aka the gis.m
GIS Manager
- oldtcltk - Old Tcl/Tk based GUI aka the d.m
Display Manager
- wxpython - New wxPython based GUI aka
wxGUI
If the -u update flag is given or the g.gisenv
GRASS_GUI variable is missing, then the GRASS_GUI
variable is permanently changed and the selected GUI will be used
as the default UI from then on.
NOTES
Valid values for GRASS_GUI are text, tcltk,
oldtcltk, and wxpython.
g.gisenv variables are stored in the user's home directory
in a hidden file called ".grassrc6". They are not shell environment
variables and the "rc" file is not a classic UNIX run command file,
it just contains persistent GRASS variables and is not executed.
