docker exec -it retail_pg ls -ltr /Users/fallout/research/data/retail_db_json 

The command above should display the folder within the retail_db_json. But it is giving me a total count of 0. I cannot understand why when it is able to iterate properly over data and research directory. Why is not working for retail_db_json? Is there something off with the command ?

The command you provided appears to be incomplete or incorrect.

The docker exec command is used to run a command in a running Docker container. The -it flag specifies that the command should be run in an interactive shell, which is necessary for some commands (like ls) to work properly.

In the command you provided, retail_pg is specified as the name of the Docker container. This is followed by the ls command, which is used to list the contents of a directory. The -ltr flags are used to show the contents of the directory in long format, sorted by modification time in reverse order.

However, the path to the directory you want to list, /Users/fallout/research/data/retail_db_json, is incomplete. The /Users directory is typically the top-level directory on a macOS system, but it is not likely to be present in a Docker container.

It is also worth noting that the ls command will only show the contents of a directory on the host system if the directory is mounted into the Docker container as a volume. If the retail_db_json directory is not mounted as a volume, the ls command will not be able to access it.

To fix the command you provided, you will need to provide the correct path to the retail_db_json directory on the host system, and ensure that the directory is mounted as a volume in the Docker container.
