<para>
The <command>newgrp</command> command is used to change the current
group ID during a login session. If the optional <option>-</option>
flag is given, the user's environment will be reinitialized as though
the user had logged in, otherwise the current environment, including
current working directory, remains unchanged.
</para>
<para>
<command>newgrp</command> changes the current real group ID to the
named group, or to the default group listed in
<filename>/etc/passwd</filename> if no group name is given.
<command>newgrp</command> 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 <filename>/etc/shadow</filename> if this
user has an entry in the shadowed password file, or in
<filename>/etc/passwd</filename> 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.
</para>
<para>
If there is an entry for this group in
<filename>/etc/gshadow</filename>, then the list of members and the
password of this group will be taken from this file, otherwise, the
entry in <filename>/etc/group</filename> is considered.
