DESCRIPTION

27       This program allows the user to control access to the  current  mapset.
28       Normally,  any  user can read data from any GRASS mapset. But sometimes
29       it is desirable to prohibit  access  to  certain  sensitive  data.  The
30       g.access  command  allows a user to restrict read and execute access to
31       the current mapset (see UNIX chmod command).  g.access will not  modify
32       write access to the current mapset.
33
34       The  user  may, for example, allow only users in the same UNIX group to
35       read data files in the mapset, or restrict the mapset to  personal  use
36       only.

NOTES

39        Under GRASS, access to the mapset PERMANENT must be open to all users.
40       This is because GRASS looks for the user's  default  geographic  region
41       definition  settings  and  the  location TITLE in files that are stored
42       under the PERMANENT mapset directory.  The g.access command, therefore,
43       will not allow you to restrict access to the PERMANENT mapset.
44
45       The  g.mapsets command isn't smart enough to tell if access to a speci‐
46       fied mapset is restricted, and the user is therefore allowed to include
47       the  names of restricted mapsets in his search path.  However, the data
48       in a restricted mapset is still protected; any attempts to look for  or
49       use  data  in  a restricted mapset will fail.  The user will simply not
50       see any data listed for a restricted mapset.
