Devlog #4

Hello!

I am now working on a big refactor (again).

I am planning to write a .sh script that can be used in either alpine or debian based image.

A rough description of what I am making from my previous Devlog:
I am making an OCI Image, basically a Docker image, that includes Nginx and a bunch of third-party modules and runs out of the box.

I was almost new to .sh scripts. I knew it is similar to the command used in Terminal, but I didn’t know there are actually some huge difference.

• case and if

  • I learned how to use the case command.
  • I learned more about the if command.
  • A quick example:

    # /bin/sh
    
    # Example for Case
    case ${YOUR_ENV} in 
    "Apple")
    echo "The ENV is Apple"
    # Ending symble
    ;;
    "Orange"|"Banana")
    echo "The ENV is either Orange or Banana"
    ;;
    # Ending symble
    esac
    
    # Example for if:
    
    # Conditions can be:
    
    [ -z ${YOUR_ENV} ] # If the ENV is empty
    [ ${YOUR_ENV} == "Hi" ] # If the ENV matches the string Hi
    
    # The space after the "[" and before the "]" is super important. It cannot be forgotten. 
    
    # Read more about the space:
    # https://www.shellcheck.net/wiki/SC1020
    
    if [ condition ]; then
         echo "The condition is True!"
    else
        echo "The condition is not True!"
    
    # Ending symble
    fi
    

More information will be provided in the next Devlog (Devlog #5 ).

So many ARGs in the photo!
