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>
|
|
<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.
