Just a note... the options -sS and -O require root privileges to be executed successfully.

Checking your own machine(s) is a good idea. Be aware that scanning other folks systems without written approval from the owner of the target is illegal in some countries. Port scanning activity is logged and many systems are configured to detect and alert for scan activity.

there is a conflict in this command. -sS is stealthy scan BUT -sV (version scan) executes tcp connection scan, meaning 3 way handshake. Therefor use 1 of them, depending on the needs.

Besides, there is no need to put -sS because that's the default in nmap.
