NEWGRP(1) NEWGRP(1)
NAME
newgrp - log in to a new group
SYNOPSIS
newgrp group
DESCRIPTION
Newgrp changes the group identification of its caller, anal-
ogously to login(1). The same person remains logged in, and
the current directory is unchanged, but calculations of
access permissions to files are performed with respect to
the new group ID.
A password is demanded if the group has a password and the
user himself does not.
When most users log in, they are members of the group named
`other.' Newgrp is known to the shell, which executes it
directly without a fork.
FILES
/etc/group, /etc/passwd
