Error when I do exercise about Learn Bash and SQL by Building a Bike Rental Shop - Build a Bike Rental Shop

[nguyenquanganh]

I try to do exercise about Learn Bash and SQL by Building a Bike Rental Shop - Build a Bike Rental Shop until the exercise: Move the echo command that prints all the available bikes below the message you just added, i try do add echo "$AVAILABLE_BIKES", it was true but I try to click Run to pass it was error many times: `. I tried to reset many times and do again but was error many times.

Here is my source code:

#!/bin/bash

PSQL="psql -X --username=freecodecamp --dbname=bikes --tuples-only -c"

echo -e "\n~~~~~ Bike Rental Shop ~~~~~\n"

MAIN_MENU() {
  if [[ $1 ]]
  then
    echo -e "\n$1"
  fi

  echo "How may I help you?" 
  echo -e "\n1. Rent a bike\n2. Return a bike\n3. Exit"
  read MAIN_MENU_SELECTION

  case $MAIN_MENU_SELECTION in
    1) RENT_MENU ;;
    2) RETURN_MENU ;;
    3) EXIT ;;
    *) MAIN_MENU "Please enter a valid option." ;;
  esac
}

RENT_MENU() {
  # get available bikes
  AVAILABLE_BIKES=$($PSQL "SELECT bike_id, type, size FROM bikes WHERE available = true ORDER BY bike_id")
  echo "$AVAILABLE_BIKES"

  # if no bikes available
  if [[ -z $AVAILABLE_BIKES ]]
  then
    # send to main menu
    MAIN_MENU "Sorry, we don't have any bikes available right now."
  else
    # display available bikes
    echo -e "\nHere are the bikes we have available:"
    echo "$AVAILABLE_BIKES"
    # ask for bike to rent

    # if input is not a number

    # send to main menu

  fi
}

RETURN_MENU() {
  echo "Return Menu"
}

EXIT() {
  echo -e "\nThank you for stopping in.\n"
}

MAIN_MENU

You have copied the echo command to the correct place, but you also need to delete the original echo command (i.e. it should be moved rather than copied).

i am curently facing the same issue, have you managed to solve it? how did you do it?

Thank you you saved me.

[sharkguo1279]

look at the red line，you have typed a code line “echo “$AVAILABLE_BIKES””,so, you must delete it
