What is the usage of the nmap command?

Nmap (Network Mapper) is an open-source network security scanning tool used to discover hosts and services on a network. It can scan for open ports on target hosts, determine the operating system, identify running services, and perform vulnerability detection. Here are some common use cases for Nmap commands:

1. Basic scanning: Scan the open ports of the specified target host using the following command.
2. scan the target host with nmap
3. Scan specified ports: Use the following command to scan specific ports on a target host.
4. Scan the target host for open ports using Nmap.
5. Scan multiple target hosts: Use the following command to scan multiple target hosts.
6. scan multiple target hosts using nmap
7. Scan multiple port ranges: Use the following command to scan multiple port ranges on the specified target host.
8. Scan ports from [starting port number] to [ending port number] on [target host] using nmap.
9. Scan specific network: Use the following command to scan all hosts on the specified network.
10. scan network addresses with nmap using CIDR notation
11. Scan a designated range of hosts: Use the following command to scan all hosts within the specified range of hosts.
12. Scan the range of hosts from [starting host IP address] to [ending host IP address] using nmap.
13. Specify scanning speed: Use the following command to specify the speed of the scan (1-5, 1 being the slowest and 5 being the fastest).
14. Scan the target host with nmap using the specified scan speed.
15. Identifying the operating system: Attempt to identify the operating system of the target host using the following command.
16. Scan the target host using nmap for operating system detection.
17. Service and Version Detection: Use the following command to try to identify the services and versions running on the target host.
18. nmap -sV [target host]
19. Vulnerability scanning: Use the following command to scan for known vulnerabilities on the target host.
20. Scan with nmap using the specified script against the target host.

These are just a few commonly used examples of Nmap commands. Nmap also offers many other features and options that can be further explored and utilized based on specific needs.
