It skips host discovery (-Pn), performs a SYN scan (-sS), scans every TCP
port (-p-), detects service versions (-sV), attempts OS fingerprinting
(-O), enables advanced detection (-A), runs the vulnerability NSE scripts
(--script=vuln), explains why ports are in each state (--reason), and even
traces the route to the target (--traceroute).
It's not a command I'd run casually against every host, but it's a great example
of how much information Nmap can gather in a single scan when you're performing
an authorized security assessment.

Interesting. I never got much in the pen-testing area, security, or scanning things, but I like to know those things nonetheless.
