NAME
    newgrp - log in to a new group

SYNOPSIS
    newgrp [ group ]

DESCRIPTION
    Newgrp changes the group identification of its caller, analogously to
    login(1). The same person remains logged in, and the current directory
    is unchanged, but calculations of access permissions to files are per-
    formed with respect to the new group ID.

    If no group is specified, the GID is changed to the login GID.

FILES
    /etc/group
    /etc/passwd

SEE ALSO
   login(1), group(5)
