I've been searching for a while to try to find a solution to this, not
sure if there is one. This is the set up:

I have two directories, one is /home/shared/images where I keep image
files that all users share, the other is /home/mearns/images which is
where I keep my own images that other users don't have access to. In
order to simplify image browsing for myself, I want to have links for
all of the files in the shared images directory in my personal image
directory. In otherwords, when I ls in my personal image directory, I
want to see the actual contents of that directory PLUS the contents of
the shared image directory.

I know it's easy enough to write a shell script to automatically
create links for all the files in the shared directory, but it won't
update when I add files to the shared directory, or rename files, or
whatever. I basically want a live view of the shared directory, merged
with a live view of my personal directory. I know can link the shared
directory itself, but I don't want it to look like a seperate
directory in my personal folder.

Does anyone know of a way to do this? If there's no command to do it,
is there a way to set up a listener for the shared folder that will
run a custom shell script everytime the directory contents change?

Thanks,
-Brian

Hi Brain,

I have a question to ask you.Is it the users you create under the /
home or simply you create up a directory over there ..??Or different
machines??

Individual user cannot able to see each other by default.

Thank You

Hi Melbin,

Yes, I know that, thanks. shared is an actual user, but I've chown'd
and chmod'd it's home directory so that users in a specific group have
full access to it. (I basically just set it up as an actual user so I
cd to ~shared and it will know where to go).

The access isn't really the issue: forget /home/shared, it could be
any other path. The idea is just to setup a link so the contents of
one directory show up directly inside another directory. For example,
I have to these two directories, with the given contents:

/dir1
====
/dir1/d1_file1
/dir1/d1_file2

/dir2
====
/dir2/d2_fileA
/dir2/d2_fileB

I want to set up something so that when I get a directory listing for /
dir1, it will show up with all four file:

ls /dir1
d1_file1
d1_file2
d2_fileA
d2_fileB

where the d2* files are actually links to the files in /dir2. But I
want to do this without actually creating the individual file links so
that, for instance, when I add a file to /dir2, for instance, the link
to it automatically shows up in /dir1

Is that more clear?
Thanks.

-Brian
