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.

A password is demanded if the group has a password and the user himself does not.

Newgrp is known to the shell, which executes it directly without a fork.

FILES
/etc/group, /etc/passwd

SEE ALSO
login(1), group(5)
