Can adding to a new group be effective in current login environment without re-login?
Hey folks,
When a user is added to a new group, the user has to be log out and log in again to make the new group effective. Is there any system command or technique to refresh user group ID update without re-login?
I am not talking about to use "login" or "su -l" commands which can only make it effective in the terminal when the re-login command is running.
What I am looking for is a set of system commands which can refresh the user group IDs across the current login environment. Or it is not possible to add new group without re-login?
Thank you.
Kind regards.

newgrp
NEWGRP(1) BSD General Commands Manual NEWGRP(1)
NAME
newgrp -- change to a new primary group
SYNOPSIS
newgrp [-l] [group]
DESCRIPTION
The newgrp command changes a user to a new primary group (real and effective group ID) by starting a new shell. The user remains logged in
and the current directory and file creation mask remain unchanged. The user is always given a new shell even if the primary group change
fails.
The newgrp command accepts the following options:
-l The environment is changed to what would be expected if the user actually logged in again. This simulates a full login.
The group is a group name or non-negative numeric group ID from the group database. The real and effective group IDs are set to group or the
group ID associated with the group name.
If group is not specified, newgrp restores the user's real and effective group IDs to the user's primary group specified in the password
database. The user's supplementary group IDs are restored to the set specified for the user in the group database.
If the user is not a member of the specified group, and the group requires a password, the user will be prompted for the group password.
FILES
/etc/group The group database
/etc/master.passwd The user database
/etc/passwd A Version 7 format password file
EXIT STATUS
If a new shell is started the exit status is the exit status of the shell. Otherwise the exit status will be >0.
SEE ALSO
csh(1), groups(1), login(1), sh(1), su(1), umask(2), group(5), passwd(5), environ(7)
STANDARDS
The newgrp command conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
A newgrp command appeared in Version 6 AT&T UNIX. A newgrp command appeared in NetBSD 5.0.
BUGS
There is no convenient way to enter a password into /etc/group. The use of group passwords is strongly discouraged since they are inherently
insecure. It is not possible to stop users from obtaining the encrypted password from the group database.
