title: /bin/bash: scripts/script.sh: Permission denied
body: <p>I am testing how to install a sample network for Hyperledger Fabric. when I was running 'byfn.sh' inside the 'first-network' project, the console will prompt such error:</p>
  
  <blockquote>
    <p>/bin/bash: scripts/script.sh: Permission denied</p>
  </blockquote>
  
  <p>it looks like this line produces above error:</p>
  
  <blockquote>
    <p>docker exec cli scripts/script.sh $CHANNEL_NAME $CLI_DELAY $LANGUAGE $CLI_TIMEOUT $VERBOSE</p>
  </blockquote>
  
  <p>I used root user, and have used <strong>chmod +x</strong> or <strong>u+x</strong> to change all *.sh files permission. but doesn't work, so any ideas? many thanks!!</p>
