Accessing Environment Variable in Shell Script

Question

I'm trying to create a shell script that sets an environment variable and then calls another shell script which gets that environment variable. The following code is my attempt, but it's not producing the desired result...

scriptOne.sh

export MYVAR=blob                                                            
bash ./scriptTwo.sh

scriptTwo.sh

#!/bin/bash                                                                     
# SIMPLE                                                                        

printenv MYVAR <<END                                                            
ls || pwd && ls                                                                 
ls || ls | wc || pwd && ls                                                      
END                                                                             
echo

What does redirecting input to printenv do?

Try $MYVAR in scriptTwo.sh you need to add a dollar to expand a shell variable. I think you can call it using simply $ bash scriptTwo.sh btw.
