bash - Show active ip-addresses in linux script with % or UP/DOWN -

i have ip-address: 192.168.0.205 can ping in script:

for in 192.168.0.205 ....   ping -c 1 $i done 

but want script shows: 192.168.0.205 or down

is there way show in % e.g: 75% up?

what may want this:

x=0; a=1 b=5 for((i=$a;i<=$b;i++))     y=`ping -n 1 192.168.1.$i | grep unreachable | wc -l`     x=$(($x + $y)) done; echo "$x $b $a" | awk '{printf "%.2f %% down\n",($1/($2-$3+1))*100}'; 

x: contains number of down ips

a: last octet of first ip address

b: last octet of last ip address

y: contains 0 if ip else 1

i hope helps!

ps: change -n -c or whatever option work in shell!
