I would like to change my default group.
I tried using newgrp, but it will change the group in that xterm only.
If i open a new xterm that setting is gone.
Also i tried by putting newgrp <my_grp> into the file .cshrc which will be run during startup. Eventhough its working, it is giving a lot of errors while a new xterm is opened. Also i am not able to exit, the windoe remains open even if i give exit command.
