impd to pbd

Hello friends

Using datapump I am trying to import into a pluggable database (pdb), but I cannot do it using my script. My script is something like this:

oracle 19c

ORACLE_BASE=/oracle/base
ORACLE_HOME=/oracle/home
ORACLE_SID=cdb02
ORACLE_PDB_SID=genesis
#SERVICE_NAME=genesis
PATH=/home/oracle/.local/bin:/home/oracle/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/oracle
/.local/bin:/home/oracle/bin:/home/oracle/bin:/oracle/home/bin:/bin

export ORACLE_BASE
export ORACLE_HOME
export ORACLE_SID
#export ORACLE_PBD_SID
export SERVICE_NAME
export PATH

#! /bin/sh
