+ <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.
