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.
