A few minutes ago I completed this little ping script,
for non initiated users.

It first pings the 192.168.1.1
then pings the 192.168.2.1
after that it pings the 8.8.8.8
and finally pings the www.google.com address

Why does it pings 1.1 and 2.1 ?

Because my friend wanted to use it in different areas, ( he his not familiar with the shell ) for example at work 1.1 and home 2.1.

Why does it pings 8.8.8.8 and google.com ?

Similar as above  8.8.8.8 is the DNS of google .. and  google.com is just reaching the web

How does it work ? :

Execute the script.sh and it will print out  5 pings to 1.1  and write the result in GREEN / RED and then 5 pings to 2.1 and the result in GREEN / RED
and so one.

The script :

#!/bin/sh
GREEN="\\033[1;32m"
NORMAL="\\033[0;39m"
RED="\\033[1;31m"
clear
####################### 1.1 ################
ping -c 5 192.168.1.1
if [ ! "$?" -eq 0 ]; then
echo -e "$RED" "ping 1.1 failed" "$NORMAL"
else
echo -e "$GREEN"  "ping 1.1 passed" "$NORMAL"
fi
########################## 2.1 ##############
ping -c 5 192.168.2.1
if [ ! "$?" -eq 0 ]; then
echo -e "$RED"  "ping 2.1 failed" "$NORMAL"
else
echo -e "$GREEN" "ping 2.1 passed" "$NORMAL"
fi
########################## 8.8 ##############
ping -c 5 8.8.8.8
if [ ! "$?" -eq 0 ]; then
echo-e "$RED" "ping 8.8 failed" "$NORMAL"
else
echo -e "$GREEN" "ping 8.8 passed" "$NORMAL"
fi
########################## GOOGLE ##############
ping -c 5 www.google.com
if [ ! "$?" -eq 0 ]; then
echo -e "$RED" "ping google failed" "$NORMAL"
else
echo -e "$GREEN" "ping google passed" "$NORMAL"
fi

So have fun
