NEWGRP(1)                        User Commands                       NEWGRP(1)



NAME
       newgrp - log in to a new group

SYNOPSIS
       newgrp [-] [group]

DESCRIPTION
       newgrp is used to change the current group ID during a login session. If the
       optional - 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.


       newgrp 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.  newgrp 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.

       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.
