Issue

I'm trying to make a bash script that asks me a question and, if I respond y, executes the subsequent scripts; but, if I respond n, it terminates "ALL" of the subsequent script.

I already created the bash script, but when I respond with n, the following scripts, build and anotherBashScript, are executed.

package.json

  "scripts": {
    "prebuild": "./ask.sh",
    "build": "vite build",
    "postbuild": "./anotherBashScript.sh"
  },

ask.sh

read -p "Are you sure you want to build the app? (y/n) " yn

case $yn in 
    [yY] ) echo Building the app...
        break;;

    [nN] ) echo exiting...;
      
        exit 1;;

    * ) echo invalid response;;
esac

Thanks Raman Sailopal.

I adapted your suggestion and applied it to write the following script, and it was successful!

package.json


  "scripts": {
   "prebuild": "./ask.sh",
   "build": "./build.sh",
   "postbuild": "./anotherBashScript.sh"
 },

ask.sh

#! /bin/bash

read -p "Are you sure? (y/n) " yn

case $yn in
[yY])
    echo Building the app...
    echo 1 >status.txt
    ;;
[nN])
    echo exiting...
    ;;
*) echo invalid response ;;
esac

build.sh

#! /bin/bash

if [[ "$(cat status.txt)" == "1" ]]; then
  yarn run vite build
  echo 1 >status.txt
  exit 1

else
  exit 1
fi

anotherBashScript.sh

#! /bin/bash

if [[ "$(cat status.txt)" == "1" ]]; then
      # do stuff
      rm status.txt


else
      exit 1
      rm status.txt
fi
