and Grepable format, respectively, to the given filename.
-oA : Output in the three major formats at once
-v: Increase verbosity level (use -vv or more for greater effect)
-d: Increase debugging level (use -dd or more for greater effect)
–reason: Display the reason a port is in a particular state
–open: Only show open (or possibly open) ports
–packet-trace: Show all packets sent and received
–iflist: Print host interfaces and routes (for debugging)
–append-output: Append to rather than clobber specified output files
–resume : Resume an aborted scan
–stylesheet : XSL stylesheet to transform XML output to HTML
–webxml: Reference stylesheet from Nmap.Org for more portable XML
–no-stylesheet: Prevent associating of XSL stylesheet w/XML output
MISC:
-6: Enable IPv6 scanning
-A: Enable OS detection, version detection, script scanning, and traceroute
–datadir : Specify custom Nmap data file location
–send-eth/–send-ip: Send using raw ethernet frames or IP packets 隐藏IP
–privileged: Assume that the user is fully privileged
–unprivileged: Assume the user lacks raw socket privileges
