NAME

newgrp - Change group ID sg - Execute command as different group ID

SYNOPSIS

newgrp [__-__? [''group''? sg [__-__? [''group'' [[[[__-c__? command]]

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. The user will be prompted for a password if they do not have a password 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 sg command works similiar to newgrp but does not replace the user's shell, so upon exit from a sg command, you are returned to your previous group ID. sg also accepts a command. The command will be executed with the Bourne shell and must be enclosed in quotes.
