Appending Nmap output logs
By default, Nmap overwrites logfiles when any of the output options are used: (-oN, -oX, -oG, and -oS). To append the results instead of overwriting them, use the directive --append-output, as shown in the following command:
$ nmap --append-output -oN existing.log scanme.nmap.org
With XML files, Nmap will not rebuild the tree structure. If you plan on parsing or processing the results, I recommend that you do not use this option unless you are willing to fix or split the files manually.
