The command used to list all Docker images on a local machine is "docker images." This command provides a comprehensive overview of the images available in the local Docker environment, displaying details such as the repository name, tag, image ID, creation date, and size. This information is crucial for managing images effectively, allowing users to identify which images are stored locally and their relevant metadata.

Other commands mentioned, like "docker ps," serve a different purpose. This command lists all the running containers, not images. "docker list" is not a valid Docker command, as it doesn't exist in the Docker CLI. Similarly, "docker ls" is not a recognized command; the correct usage related to the listing of images is "docker images." Thus, the choice of "docker images" is the appropriate one for obtaining a list of all Docker images on the local machine.
