I have this:

```
$ ls -l test1.sh 
-rwxr-sr-x 1 root root 24 2011-05-31 13:27 test1.sh # sgid root

$ id
uid=1001(abc) gid=1001(abc) groups=4(adm),6(disk),20(dialout),21(fax),24(cdrom),26(tape),29(audio),30(dip),44(video),46(plugdev),104(  fuse),106(lpadmin),112(netdev),121(admin),122(sambashare),1001(abc),1002(sbox)

```

But, when I run test1.sh, I do not see the Effective Group Owner to be root in ps o/p.. why ?

```
$ ps -o pid,ppid,cmd,euid,euser,ruid,ruser,egid,egroup,rgid,rgroup,nice,tty,user

  PID  PPID CMD                          EUID EUSER     RUID RUSER     EGID EGROUP    RGID RGROUP    NI TT       USER
