.SH "SYNOPSIS"

\fBnewgrp\fR [\-] [\fIgroupe\fR]
.SH "DESCRIPTION"
.PP
The
\fBnewgrp\fR
command is used to change the current group ID during a login session\&. If the optional
\fB\-\fR
flag is given, the user\*(Aqs environment will be reinitialized as though the user had logged in, otherwise the current environment, including current working directory, remains unchanged\&.

\fBnewgrp\fR
changes the current real group ID to the named group, or to the default group listed in
/etc/passwd
if no group name is given\&.
\fBnewgrp\fR
also tries to add the group to the user groupset\&. If not root, the user will be prompted for a password if she does not have a password (in
/etc/shadow
if this user has an entry in the shadowed password file, or in
/etc/passwd
otherwise) and the group does, or if the user is not listed as a member and the group has a password\&. The user will be denied access if the group password is empty and the user is not listed as a member\&.
.PP
If there is an entry for this group in
/etc/gshadow, then the list of members and the password of this group will be taken from this file, otherwise, the entry in
/etc/group
is considered\&.
