Each of these shell scripts is critical to the usability of the images we're building.

Follow these steps:

1. In a file called build. sh, enter the following text and save it:

#/bin/bash
nvidia-docker build -t ch6 . 

2. Make the sure the script is executable by issuing this at the Terminal window:

chmod +x build.sh

3. Execute the script to build the image:

./build.sh

4. Open a build called clean.sh, add the following text, and save:

#/bin/bash
docker rmi ch6

5. Make the sure the script is executable by issuing this at the Terminal window:

chmod +x clean.sh

6. Only use the clean.sh script if you need to remove the container and rebuild from scratch.
