chmod g+s
Hi everybody
Does anyone have an idea why is not possible to set the gid bit on a directory using the octal mode (like: chmod 2755 /dir)? The only way this works is by using the symbolic mode: chmod g+s /dir Why? Where is the logic in that?

Probably depends on your OS. What are you using anyway? For the record, it works just fine for me on RedHat Linux 9. I could test it with BSDs as well and see what happens.
Code:
[root@ironmaiden foo]# mkdir bar [root@ironmaiden foo]# ls -l total 4 drwxr-xr-x 2 root root 4096 Apr 1 03:05 bar [root@ironmaiden foo]# chmod 02755 bar [root@ironmaiden foo]# ls -l total 4 drwxr-sr-x 2 root root 4096 Apr 1 03:05 bar

chmod g+s
I am using Solaris. And here is what happens:
# mkdir test1 # chmod 2755 test1 # ls -ld test1 # drwxr-xr-x 2 root other ... # chmod g+s test1 # ls -ld test1 # drwxr-sr-x 2 root other ... It can be really tricky if one is not aware of this. I'm just trying to understand what is the reason for this limitation
