i want to login as a member of non primary group to create files whose owner as a member of non primary group of current user.
-rwxr-xr-x 2 gowtham gowtham 4096 Sep 5 14:48 defaultNewFile
drwxr-xr-x 2 gowtham specificgrp 4096 Sep 5 14:50 requiredNewFile
i don't want to change group ownership after creation of file with chown.
I am more interested in login as a member of a non primary group.
