How to implement a value input as part of a parameter?

Question

bash

Tell me how to implement the construction when there is a yes / no condition during the script startup . And if the answer is yes - you will need to add a key and a custom value. If the answer is no - just continue the script execution. key "value". Where keyis a constant value, and value- is entered by the user after running the script. Separately, I know how to do it, but it's impossible to connect.

Answer 1

It's not entirely clear what exactly doesn't work, but here's an example

#!/bin/bash

 echo "Yes or No?"
 read -p "Answer: " varanswer
 echo $varanswer
if [ "$varanswer" = "Yes" ]; then
    read -p "KEY: " varkey
    echo $varkey
else
    echo "do script"
fi

Answer 2

Form the command line in pieces and assemble it from the pieces at startup.
