Send a ping to each IP on a subnet

Question

Is there a command line based way to send pings to each computer in a subnet? Like

for(int i = 1; i < 254; i++)
    ping(192.168.1.i);

t

Answer 1

#!/bin/sh

COUNTER=$1

while [ $COUNTER -lt 254 ]
do
 echo $COUNTER
 ping -c 1 192.168.1.$COUNTER | grep 'ms'
 COUNTER=$(( $COUNTER + 1 ))
done

#specify start number like this: ./ping.sh 1
#then run another few instances to cover more ground
#aka one at 1, another at 100, another at 200
#this just finds addresses quicker. will only print ttl info when an address resolves
