i new in linux, i want ask:
how to use sgid and sticky bit for special permission ?

What specifically are you trying to do? In general, the sticky bit is set for world writable directories (i.e. anyone can access and change the directory contents) and the suid and sgid bits are set for executable files (e.g. PERL scripts).

What the sticky bit does to a world writable directory is limit any changes that a user might want to make to that directory to only the files that the user owns. In other words, any user can make any changes to the directory, but only to files that they own in that directory. A good example of the sticky bit in action is the /tmp directory.

When the suid and sgid bits are set for an executable file, the executable file runs with the privileges of the file's owner and/or group, depending on which bits are set. This can be quite useful for a PERL script on a website because it will allow the script to access data that the caller of the script (i.e. the web surfer) can be prevented from accessing. In other words, it greatly enhances a website's security.

I have four user is:
- jack with secondary group manager, sysadmin, admin, webdev
- jenny with secondary group admin
- brian with secondary group webdev, sysadmin
- steven with secondary group sales
i want jenny couldn't access webdev and sysadmin then brian couldn't access admin

Could you make this more clear. What you wrote here makes no sense to me.

- user jenny can't access to webdev and sysadmin group
- user brian can't access to admin group

Set your users up as follows?:

- jack with secondary group manager, sysadmin, admin, webdev
- jenny with secondary group sysadmin, admin, webdev
- brian with secondary group admin, webdev, sysadmin
- steven with secondary group sales
