Shell script to Ping your Home Lan Network

i wrote a simple shell script which ping the provided range of ip in a Lan network and shows the host is up or down.

ping.sh

 #!/bin/bash  
 # ./ping.sh <starting_address> <end_address>  
 # ./ping.sh 100 120  
 #  
 for((x=$1;x<=$2;x++))  
 do   
     ping -W1 -c1 192.168.0.$x > /dev/null  
      if [ $? -eq 0 ]  
     then  
         echo "host 192.168.0.$x : Up"  
     else  
         echo "host 192.168.0.$x : Down"  
     fi  
 done  

Now lets run it

./ping.sh 100 120

Thanks..
