I recently started bash scripting and got stuck with a very basic usecase, searched stackoverflow/google but couldn't find a way to achieve what I am trying to do.
I have a script color.sh
#!/bin/bash
Apple="Red"
Orange="Orange"
Banana="Yello"
echo $$1
What I am trying to achieve is print the color of fruit and accept fruit from command line. The output I want is
./color.sh Apple -> Red, but what I get is some random number which I think is process Id.

Is there a way to echo that exact command they typed from inside the script?
I've tried echo !! which does not work inside a script.

I was reading this question where I saw not one but two separate answers where the code provided used a form of echo( with no closing parenthesis.
What does this form of the command do?
I am familiar with echo. to perform an echo of an empty line but I've not seen this other form before.
