I set all of the environment variables from a ~/.bashrc.grass file which is sourced by my ~/.bash_profile file, so GRASS commands work everywhere. The environment variables are initially set to use 7.0-svn. But each version of GRASS which I have checked out has a copy of the scripts. "source"ing the script will cause that particular version of GRASS to become "active", i.e. $GISBASE, $PATH, $LD_LIBRARY_PATH and $PYTHONPATH will all refer to the copy of GRASS in $PWD/dist.i686-pc-linux-gnu. -- Glynn Clements <[email protected]> _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
