## DESCRIPTION

This program allows user to start a selected graphical user interface (GUI) from the command line prompt.

GRASS 7 has a new GUI based on wxWidgets, written in Python:

- wxpython - New wxPython based GUI aka wxGUI

The old gis.m and d.m Tcl/Tk GUIs from GRASS 6 have been removed.

If the -u update flag is given or the g.gisenv `GUI` variable is missing, then the `GUI` variable is permanently changed and the selected GUI will be used as the default UI from then on.

## NOTES

Valid values for GUI variable are `text` and `wxpython`. g.gisenv variables are stored in the user's home directory in a hidden file called "`.grass7/rc`". 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.
