NEWGRP(1)

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 performed 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)
