Hi,

If you you want a quicker execution - you could also run the pings to separate hosts in parallel starting the jobs in background (&) and waiting for them with "wait" after that. You'll have to be more careful about the outputs in that case - e.g. redirect them to separate files.

    Do you mean something like:
    ping -c10 host1
    ping -c10 host2
    ....
    which will ping host1 10 times, then host2 10 times etc. (see
    `man ping` for details of the options).

    If you have a list of hosts in a file, you could do:
    for host in `cat [filename]`
    do
           ping -c10 $host
    done

    or:

    while read host
    do
           ping -c10 $host
    done << [filename]

    If you only want to ping each host once, you can substitute
    '-c10' with '-c1' (again, see the man page).

    Hope this helps
    Laurence
