Hi, all Suppose that in a FC6 system there are two users, user01 and user02. Both are members of the group users, which is their primary group. They're not members of the group root. There is a directory named /test: drwxrwx--- 2 root users 4096 Dez 26 12:42 test/ In this directory, there is a file named file.txt: -rw-r----- 1 user01 root 90 Dez 26 12:43 file.txt user02, as expected, is not able to read nor modify the contents of this file, as he does not have read nor write permissions on it. However, he can delete the file, because he has write permissions on /test, once he's member of the group users. However, if user02 opens file.txt in VIM, edit it and then save it with :w!, the file is modified, saved, and its ownership is altered to user02:users. How can this happen?? How can VIM alter the ownership and write to this file, if user02 is not it's owner and have no permissions on it? user02 can't do that using chown, chmod nor chgrp, but using VIM he can?! Thanks, Marcelo
