Added new version of the function, so there is a choice of grep or sed. Added a Home Assistant sensor setup config.

+## Costco Fuel Price script for a Home Assistant sensor
+
+### Home Assistant configuration.yaml
+
+To execute your shell script every 6 hours and expose the extracted fuel prices as sensors in Home Assistant, you'll follow these steps:
+
+1) Create the Shell Command in Home Assistant
+Ensure that the shell command integration is enabled in your Home Assistant configuration by adding this to configuration.yaml:
+
+```
+shell_command:
+  fetch_costco_fuel_prices: /config/scripts/fetch_costco_prices.sh
+```
+
+Save your script as fetch_costco_prices.sh in the /config/scripts directory or modify the path accordingly.
+
+2) Add a Command-Line Sensor for Each Variable
+Use command-line sensors to expose the extracted values. Here's how you can do it in your configuration.yaml file:
+
+```
+sensor:
+  - platform: command_line
+    name: Costco Premium Diesel
+    command: "bash /config/scripts/fetch_costco_prices.sh | jq -r '.premium_diesel'"
+    scan_interval: 21600 # Every 6 hours
+  - platform: command_line
+    name: Costco Premium Unleaded
+    command: "bash /config/scripts/fetch_costco_prices.sh | jq -r '.premium_unleaded'"
+    scan_interval: 21600 # Every 6 hours
+  - platform: command_line
+    name: Costco Unleaded Petrol
+    command: "bash /config/scripts/fetch_costco_prices.sh | jq -r '.unleaded'"
+    scan_interval: 21600 # Every 6 hours
+```
+
+Here, scan_interval: 21600 sets the sensors to update every 6 hours (21600 seconds). The command extracts the respective JSON values from the script output using jq.
+
+3) Make Sure Dependencies Are Installed
+For this setup:
+
+curl should already be installed on most systems.
+Ensure jq is installed (used to parse JSON output). On Debian-based systems, you can install it using:
+
+```
+sudo apt-get install jq
+```
+
+4) Testing the Configuration
+Before restarting Home Assistant, validate your configuration:
+
+```
+ha core check
+```
+
+If no errors are shown, restart Home Assistant to apply the new configuration:
+
+```
+ha core restart
+```
+
+This configuration will execute the script every 6 hours to retrieve the latest fuel prices and expose them as sensors in Home Assistant. You can then use these sensors in automations, dashboards, or other components as needed.
