Sure, Here's the input: [root@core2duo ~]# mkdir my_directory [root@core2duo ~]# ll -d my_directory/ drwxr-xr-x 2 root root 4096 Nov 4 08:16 my_directory/ [root@core2duo ~]# chmod g+s my_directory/ [root@core2duo ~]# ll -d my_directory/ drwxr-sr-x 2 root root 4096 Nov 4 08:16 my_directory/ [root@core2duo ~]# chmod 0755 my_directory/ #set perm in octal mode [root@core2duo ~]# ll -d my_directory/ #no effect on SGIT bit drwxr-sr-x 2 root root 4096 Nov 4 08:16 my_directory/ [root@core2duo ~]# chmod g-s my_directory/ #set perm in symbolic mode [root@core2duo ~]# ll -d my_directory/ #get back to the execution bit drwxr-xr-x 2 root root 4096 Nov 4 08:16 my_directory/ I'm confused cuz up until now I assumed the octal and symbolic mode are interchangeable and here is an example where I rather have to use a single mode to get to expected result. ________________________________ De la: Cameron Simpson <cs@xxxxxxxxxx> Către: General Red Hat Linux discussion list <redhat-list@xxxxxxxxxx> Trimis: Vineri, 4 Noiembrie 2011 1:41:37 Subiect: Re: chmod behaviour On 03Nov2011 10:22, RuceLee <bors_ruslan@xxxxxxxxx> wrote: | Recently I was playing with directory permissions on a ext4 filesystem and I have stumbled | at a situation when setting up setting up directory SGID behaves not as expected, at least for me. | | For example: | | chmod g+s my_directory works the same as chmod 2755 my_directory | | On the other hand: | | chmod g-s my_directory doesn't work the same as chmod 0755 my_directory | | the latest doing absolutely nothing to remove the intended SGID bit. | | The latest package I have is coreutils-8.4-13.el6.x86_64 You should probably post a transcript with: ls -ld my_directory before and after each chmod command just so people can see exactly what the permission state is.
