tint2-weather - a small modification

I'm using tint2-weather script executor by
addy-dclxv

#!/bin/bash

# I take this script from Anachron's i3blocks
# I only slightly modify this script to add an option to show icon
# I also remove the i3blocks specify script
# To make this works with tint2 executor, polybar custom script, dzen2 feeder, conkybar, lemonbar feeder, dunst notify, etc.
# 'weather -i' = with icon, 'weather' = text only
# Cheers!

So far, it goes smoothly with the exception of if my internet connection goes down. I would like to add a message there is no connection.
Could someone set if eth0 present (weather-url) else if no connection (con-down)

I know how to do on conky, but i'm not that good on bash.

Thanks in advance!

The bunsenweather script uses a connection test, which you could adapt I guess

connectiontest() {
    local -i i attempts=${1-0}
    for (( i=0; i < attempts || attempts == 0; i++ )); do
        if wget -O - 'http://ftp.debian.org/debian/README' &> /dev/null; then
            return 0
        fi
        if (( i == attempts - 1 )); then # if last attempt
            return 1
        fi
    done
}

A code snippet which might work is

if wget -O - 'http://ftp.debian.org/debian/README' &> /dev/null; then
    return 0
else
    notify-send "No internet connection"
    return 1        
fi

You could probably also parse the output from a ping command instead.

Thank you damo, I have difficult to adapt those two scripts you showed, but the ping output you gave me an idea because i already have a little snippets.

ping -qc1 8.8.8.8 2>&1 | awk -F/ '/^rtt/ { printf "%.2f", $5; ok = 1 } END { if (!ok) print "eth0 FAIL" }'

Edit:

I think i fixed in a way, but I'm not sure it's the right code

if ping -qc1 8.8.8.8 >/dev/null; then
 WEATHER_URL="http://api.openweathermap.org/data/2.5/weather?id=${CITY_ID}&appid=${API_KEY}&units=metric"
else
  echo "Link Down"
fi

Thank you
