Here is a simple korn shell script. You can get more fancy with scripting
based on your needs.
#!/usr/bin/ksh
for ip in $(cat iplist) #Where iplist is the file name where you have listed
all your ip addresses.
do
ping $ip
done > output.txt
It will read the ip addresses from "iplist" file and ping them. The output
will be saved in output.txt file. Your "iplist" file contains your ip
addresses in each line.
1.1.1.1
2.2.2.2
3.3.3.3
If you are feeding your /etc/hosts file from your unix box to the script.
Following script will do the trick.
#!/usr/bin/ksh
while read line
do
echo $line | read ip host junk
ping $ip
done < /etc/hosts > output.txt
It reads one line at a time from /etc/hosts. Usually first field in
/etc/hosts is IP address. So it will ping the host by ip address. This
script is not catching any comments line. You can write your routine to
ignore the comments line also.
Hope this helps.
