The -sV flag in the nmap command is used to enable version detection. When you run nmap with the -sV option, it attempts to determine the version of the services running on open ports of the target hosts. This can provide valuable information about the software and its version, which can be useful for security assessments, vulnerability scanning, and network inventory.
For example, the command:
nmap -sV <target>
will scan the specified <target> and report back the services and their versions running on the open ports.
