SGID and Sticky Bit

[chakkaradeepcc]

Hi all,

every linux user is aware of the SGID and StickyBit concept............now my question s this.....suppose user "root" creates a directory "/mnt/test" , it will be created default with group "root"..........so i change the group ownership now to my group "emp" in which i have 2 users "x" and "y".............

when i change the wonership i see that the permissions set for "test" directory does not contain Write Permission for Groups but Read and Execute are there.........so i change the rights by issuing "chmod 0775 test".............so now i have got RWX for Groups...........

now comes the part..........i set SGID for this directory.........i have to set by issuing,
"chmod 4775 test" which implies that i have to set the permissions for the file too and if it is set already, i should remember those permissions.........so now how can i remember the permissions for all the files!!.......

My Commands which describes the above sequences..
===============================================
#mkdir /mnt/test
#chgrp emp test
#chmod 0775 test
#chmod 4775 test

IS THERE ANY METHOD WHICH ALLOWS ME TO SET 'SGID' OR 'STICKYBIT' DIRECTLY TO A FILE??

thanks in advance...

There is indeed such a method. It's called 'chmod':

chmod +s /mnt/test

should do it.

You'd do the same but with +t for the sticky bit.
