14 Outputting Logs

Logging in Nmap can be provided by the -oN, -oX or -oG options. Each oneis followed by the name of the logfile. -oN outputs a human readable log, -oX

outputs an XML log and -oG outputs a grepable log. The -oA option outputs inall 3 formats, and -oS outputs in a format I’m sure none of you would ever wantto use (try it; you’ll see what I mean!)The –append-output option appends scan results to the output files you specifiedinstead of overwriting their contents.
