After logging in use 'newgrp' to change your id to anothe rgroup. All files you create will now belong to newgrp.

See man page on newgrp

From the man page for newgrp ...

A password is demanded if the group has a password and the user is not listed in /etc/group as being a member of that group. The only way to create a password for a group is to use passwd(1), then cut and paste the password from /etc/shadow to etc/group. Group passwords are antiquated and not often used.

Thanks grega,

Thanks,I checked it.It is working but we can take user
password from /etc/shadow.I have 10 number of group and I can assign only same password to all group.
But it is dangerous for security reason.
