NEWGRP(1)                   General Commands Manual                  NEWGRP(1)

NAME
       newgrp - log in to a new group

SYNOPSIS
       newgrp group

DESCRIPTION
       Newgrp changes the group identification of its caller.  The same person
       remains logged in, and the current directory is unchanged, but calcula‐
       tions  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(8), group(5)
