NAME

6       g.access

DESCRIPTION

9       This  program  allows the user to control access to the current mapset.
10       Normally, any user can read data from any GRASS mapset.  But  sometimes
11       it  is  desirable  to  prohibit  access  to certain sensitive data. The
12       g.access command allows a user to restrict read and execute  access  to
13       the  current mapset (see UNIX chmod command).  g.access will not modify
14       write access to the current mapset.
15
16       The user may, for example, allow only users in the same UNIX  group  to
17       read  data  files in the mapset, or restrict the mapset to personal use
18       only.

NOTES

21        Under GRASS, access to the mapset PERMANENT must be open to all users.
22       This  is  because  GRASS looks for the user's default geographic region
23       definition settings and the location TITLE in  files  that  are  stored
24       under the PERMANENT mapset directory.  The g.access command, therefore,
25       will not allow you to restrict access to the PERMANENT mapset.
26
27       The g.mapsets command isn't smart enough to tell if access to a  speci‐
28       fied mapset is restricted, and the user is therefore allowed to include
29       the names of restricted mapsets in his search path.  However, the  data
30       in  a restricted mapset is still protected; any attempts to look for or
31       use data in a restricted mapset will fail.  The user  will  simply  not
32       see any data listed for a restricted mapset.
