I have created a special userid ("aa") to access only one folder (testdir) on my PC. I created the following directory:
drwx------ me me testdir
I can't seem to change the permissions at all, not at the comand line, not using the GUI.
sudo chmod 0755 testdir
The command executes without error but the permissions don't change. Using the GUI I can select read and write for others from the drop down list but the minute I select it it changes back to "--".
I am the owner of the directory - so why can't I change it? I am on Ubuntu 12.04.
Secondary question: I linked a directory with lots of subdirs into testdir. So now I have a subdir called "Link to aaa". Ideally I would like the new user to browse and view this link directory structure as well. This original directory structure sits on another drive, but the new user should only be able to access the directories within the folder testdir, including the linked subtree.
I have not even tried yet to make that happen as I can't change any permissions at all.
Any help would be appreciated. I have a basic understanding of Ubuntu, but as you can probably tell I am new to Ubuntu.
