The usual method is the '>' redirect operator, like this:

    tcptraceroute ipv6.google.com 80 > /path/to/log/file

If the error message is going to STDERR (as it should be), you will need to 
redirect that instead:

    tcptraceroute ipv6.google.com 80 2> /path/to/log/file

To capture both, redirect STDOUT first, then set STDERR to match:

    tcptraceroute ipv6.google.com 80 > /path/to/log/file 2>&1
