Question

I am new to Linux and was introduced to the “&” recently. I have to run several traceroutes and store them in a single file, and I am curious if I am able to kick off these traceroutes in parallel?

I tried the following but the results in the generated file, are not kept apart? Well, that is what it seems to me.

traceroute  -n -z 100 www.yahoo.com >> theLog.log &
traceroute  -n -z 100 www.abc.com >> theLog.log &

Is what I am asking even possible to do? If so what commands should I be using?

Thanks for any direction given.

Answer 1

With the following command they are not really in parallel, but you can continue using your terminal, and the results are taken apart:

{ traceroute -n -z 100 www.yahoo.com; traceroute -n -z 100 www.abc.com; } >> theLog.log &
