Shouldn't GRASS session preserve umask set before entering it? It doesn't. It forces 0022 instead: $ umask 2 $ umask 0002 $ grass63 $ umask 0022 $ exit $ umask 0002 Maciek -- View this message in context: http://www.nabble.com/how-to-enable-write-access-for-the-UNIX-group--tf4505070.html#a12856927 Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
