I created this script to fix a WSL Permissions issues when I am running Docker Commands from NPM Run.

Also this can be serve as an example for building logic scripts for making your life easier.

The way it works is very simple:

Just execute the script from bash ./docker.exe and then you will be prompt with the allowed options.

"scripts": {
   ...
    "build:docker": "./scripts/docker.sh -b",
    "start:docker": "./scripts/docker.sh -r",
    "start:docker-testenv": "./scripts/docker.sh -t",
   ...
  },

If you want to modify it please make sure you are selecting the End of Line Sequence LF.

Cheers!
