hey there


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


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

The permissions on the directory also control what can be done to files within it. If the user doesn't have permission to create/remove files in a directory then the permissions of the file within that directory don't matter. Similarly if a user does NOT have permissions to navigate to a specific directory it won't matter if the file is 777.

There are different items for different things. You can even gain more granular control using Access Control Lists (ACLs) which would make the seeming permissions allowed by chmod appear not to work.

Yeah, that makes sense. Thanks
