ping from a file (not fping)

noir911 · 02-04-2008, 06:32 PM

Does anyone know how to ping a bunch of IPs from a file? ping < file.txt doesn't work. I don't want to use fping, rather want to make do with GNU ping that is available on every linux distro.

Thanks for any help.

If file.txt contains one IP per line, a while loop can do the trick:

Code:

while read ip
do
   if ping -c 2 -w 2 -q $ip > /dev/null
   then
       echo $ip alive
   else
       echo $ip does not respond
   fi
done < file.txt

A question, because I don't know, but couldn't the following also work? (again, if 1 IP per line)

cat file.txt | xargs ping

As I understand it, that should use each individual line of the file as an argument to separate ping commands ...

Edit: Nope, apparently it doesn't. Move along, nothing to see here
