NAMEnewgrp - log in to a new group
- newgrp [-] [group]
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.
The following configuration variables in /etc/login.defs change the behavior of this tool:
- Enable "syslog" logging of sg activity.
- User account information.
- Secure user account information.
- Group account information.
- Secure group account information.
