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)
