Howto simple Share iPhoto Libary via Symbolic Link to one or more User(s) on Mac OSX

There are some Tutorials out there, howto share the iPhoto Libary to different Users over the Share Folder, i not really like them. This Tutorial should explain you how you do this on a UNIX way without moving your Pictures etc just over a simple Symbolic Link.

First open a Terminal on your System and set your root Password (Your User should have admin rights) if you havent done that yet (ps. with this User you can anything on your System its like a God Mode) Italic shows the Commands you should execute with a Enter :

$  sudo passwd root
Password:
Changing password for root.
New password:
Retype new password:

Now Change your Current Terminal User to Root:

$ su
Password:

Watch for the Right Users that you want to use :

$ ls -la /Users/
drwxr-xr-x   6 root   admin   204 31 Mai  2008 .
drwxrwxr-t  39 root   admin  1394 14 Jan 21:53 ..
-rw-r–r–   1 root   wheel     0 25 Nov  2007 .localized
drwxrwxrwt   6 root   wheel   204 11 Nov 22:16 Shared
drwxr-xr-x+ 37 User1    staff  1258  6 Mär 10:58 User1
drwxr-xr-x+ 15 User2  staff   510 17 Aug  2008 User2

Comment out your Old iPhoto Libary from User 2 that should use the Share (Symbolic Link) of the User 1 Folder  (Tipp: Use the TAB Button on the Shell to AutoComplete Paths if they are clearly ):

$ mv /Users/User2/Pictures/iPhoto\ Library/ /Users/User2/Pictures/_iPhoto\ Library/

Make a Symbolic Link with ln (type man ln if you want to findout more) from User 1 to User 2:

$ ln -s /Users/User1/Pictures/iPhoto\ Library/ /Users/User2/Pictures/iPhoto\ Library

Set the right permission that User 2 can Read the Folder of User 1

$ chmod 770 /Users/User1/Pictures/
$ chmod -R 775 /Users/User1/Pictures/iPhoto\ Library/

And change Owner that User 2 can use the Symbolic Link that you made with the root User :

$ chown -h User2:staff /Users/User2/Pictures/iPhoto\ Library

Your Finished !

Thats it so check out the iPhoto of User 2 id should look like the iPhoto of User 1.

If you want to check out how a Symbolic Link  looks like on a Shell :

$ ls -la /Users/User2/Pictures/
lrwxr-xr-x   1 User2   staff   35  7 Mär 16:52 iPhoto Library -> /Users/User1/Pictures/iPhoto Library/

Ps. Symbolic Links are one of the coolest Features on a UNIX System ! Defently ! You can even Use them over a Network drive or IP-Tunnel with SSH ;-)

Murphys Law / Murphys Gesetz

Viel zitierter Spruch, doch keiner weiss woher ….

['mə:fis-]

ein in allen Lebensbereichen zitierter Ausspruch von Edward A. Murphy jr.: „If anything can go wrong – it will“ (deutsch „Wenn etwas schief gehen kann, dann wird es schief gehen“). Murphy testete 1949 bei der U. S. Air Force das Verhalten von Piloten bei hoher Beschleunigung; dafür waren 16 Sensoren am Körper des Piloten angebracht. Für die Verbindung der Stecker mit den Elektroden am Körper gab es je zwei Möglichkeiten. Die Wahrscheinlichkeit, alle Verbindungsstecker falsch anzubringen, betrug 1 : 65535. Als ein Testpilot dennoch alle Stecker falsch verband, formulierte Murphy seinen Lehrsatz.
