# How to add user into group, and make changes take effect *without logout/login*: the *newgrp* command 
#
# Do note that this method will only update the groups, in the current shell session (and its child-processes).
# New shell sessions will not have the groups updated - either use this method to update the groups in each shell 
# session, or logout/login to make the group update permanent by default 
#
# In short: 
#     $ sudo adduser user_x my_grp
#     $ newgrp my_grp && newgrp
#
