DESCRIPTION

       This  program  allows the user to control access to the current mapset.  Normally, any user can read data
       from any GRASS mapset. But sometimes it is desirable to prohibit access to certain  sensitive  data.  The
       g.access  command allows a user to restrict read and execute access to the current mapset (see UNIX chmod
       command).  g.access will not modify write access to the current mapset.

       The user may, for example, allow only users in the same UNIX group to read data files in the  mapset,  or
       restrict the mapset to personal use only.

NOTES

       Under  GRASS,  access to the mapset PERMANENT must be open to all users.  This is because GRASS looks for
       the user’s default geographic region definition settings and the location TITLE in files that are  stored
       under  the  PERMANENT  mapset directory.  The g.access command, therefore, will not allow you to restrict
       access to the PERMANENT mapset.

       The g.mapsets command isn’t smart enough to tell if access to a specified mapset is restricted,  and  the
       user  is  therefore  allowed to include the names of restricted mapsets in his search path.  However, the
       data in a restricted mapset is still protected; any attempts to look for or  use  data  in  a  restricted
       mapset will fail.  The user will simply not see any data listed for a restricted mapset.

       UNIX filesystem access controls and g.access actions are not supported by MS-Windows.
