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.ac-
cess 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 un-
der 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 speci-
fied 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.
