But will sticky bit (t-bit) not do it for you? It does exactly what you want right? That is even an option in the GUI (under file access)...
On a side note, your interpritation of how it should work is not considerate of several things. For example, you can't hide executables rights as a subsidary to read permissions. Yes, it is true that you need to read a file in order to excute it. But that is only because your interpreter needs to have those right (bash, python, curl, perl, etc.). However, in Linux many binary files can be executed without read permissions. You cannot just bundle the two :)
Anyway, Linux works in this way and probably for a reason.
Hi Hopchen , thanks for mentioning the "Sticky-bit", which seems to be a great workaround for certain circumstances in the absence of a true delete right. Will explore that a little bit for better understanding. Kind regards
For those who wonder "why", here it is: To prevent accidental deletions. In the workplace, one needs to assume that the authorized users will not attempt to sabotage the server. But accidents happen. On a share I used to administer at work, a user accidently dragged one folder into another, causing several automated processes to start failing. Fortunately, I figured it out and restored the folder to it's rightful place. But had he accidently deleted it, I would have had to rely on snapshots to restore it, and work performed after the snapshot was taken would have been lost.
Windows users often don't pay strict attention to the pop-up warning when deleting files. And they are spoiled by the Recycle Bin, as they can recover from most oopses. There being no recycle bin on a ReadyNAS (which there used to be in OS4.x and should optionally still be), there is less oops protection.
