<para>
|
|
<command>newgrp</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
|
|
/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.
|
|
</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.
