Links to Directories

[SeaSoft Systems]

<amateur hour>

I have a large scenery database (Roughly 100 directories each 
containing roughly 100 files) which is used by several copies of a 
flight simulator I am helping to beta-test (X-Plane). The database is 
a couple of gigabytes, and I have been trying to get the various beta 
versions (each contained in their own separate directories) to find 
the data without actually having to make multiple copies of the 
database.

- OSX aliases of the database folders do not work (the simulator 
evidently can't follow the aliases for some reason).

I have fussed around with ln, but the man entry is a little vague 
about whether I can use it to link directories. I am working under 
the assumption that I can, but I haven't been able to get it to work 
so far.

The top-level scenery folders all have a leading "+" (e.g., are named 
+50+020, etc.; they are latitude/longitude based).

I first tried, from within the database root directory, to do a

	ln +* /Destination/Directory/

thinking this would create directory links in /Destination/Directory/ 
for the 100 or so scenery folders.

The operation failed with an "operation not permitted". Thinking 
permission issues, I tried with sudo, but still no dice.

I then tried to link a single folder (classic case of trying to learn 
how to walk after running proves too hard :), but that failed in the 
same way:

	ln '+30+120' '/Users/rjh/X-System 740/Resources/Earth nav data/'

Can anyone point me to the right tool/procedure/syntax to accomplish this?

OS 10.2.8, tcsh

Thanks for any guidance,
