Hi all

I've got the following[1] script from the Internet ( by googling ).... 
but it is not working :-(

can anyone tell me what is wrong with it ????

[1]------------------
#!/bin/sh

for host in `awk '/^[0-9]/ { print $1 }' /home/jk/nethost`
do
	echo "Checking $host: \c"
	ping $host 1 2>&1 | \
	   sed 's/.*no answer.*/[31;1m&[0m/;s/.*is alive.*/[32;2m&[0m/'
done

--------------------------

the output of "cat /home/jk/nethost" is as under

172.16.10.1
172.16.20.1
172.16.30.1
172.16.40.1
172.16.50.1
172.16.60.1
172.16.70.1
