I have a problem in understanding the point of a sticky bit, since what it was supposed to do, it's already been done via regular permissions...i might be doing this in a wrong way, but here's an example
user x and user y are from the same group
logging as user x
$ chmod 1777 filexy
$ chmod 777 filez
logging as user y
prompts an error about permission denied... all good
prompts the same exact error...shouldn't i be able to delete this file with any user, even more if i'm from the same group as the user x?
This is my doubt. the sticky bit looks pointless because even with not setting that special bit, every other user can't remove a file or directory unless it's the owner.
Working on a Debian system, in a virtual machine.
Thanks in advance
