|Simplified Manual Pages
The standard set of manual pages (often called man pages) which are available in most flavours of Linux, BSD and Unix tend to be long and they can be cryptic. Manual pages tend to list what options are available without explaining why we might use them. Further, many manual pages do not provide examples.
The TLDR-pages project has compiled a collection of simplified manual pages which present commands with a clear explanation of what each command does and lists examples of how the command is most often used. These simplified pages are available below.
Network exploration tool and security / port scanner.
Some features only activate when Nmap is run with root privileges.

- Check if an IP address is up, and guess the remote host's operating system:
nmap -O ip_or_hostname
- Try to determine whether the specified hosts are up (ping scan) and what their names are:
nmap -sn ip_or_hostname optional_another_address
- Also enable scripts, service detection, OS fingerprinting and traceroute:
nmap -A address_or_addresses
- Scan a specific list of ports (use '-p-' for all ports from 1 to 65535):
nmap -p port1,port2,...,portN address_or_addresses
- Perform service and version detection of the top 1000 ports using default NSE scripts; writing results ('-oN') to output file:
nmap -sC -sV -oN top-1000-ports.txt address_or_addresses
- Scan target(s) carefully using 'default and safe' NSE scripts:
nmap --script "default and safe" address_or_addresses
- Scan web server running on standard ports 80 and 443 using all available 'http-*' NSE scripts:
nmap --script "http-*" address_or_addresses -p 80,443
- Perform a stealthy very slow scan ('-T0') trying to avoid detection by IDS/IPS and use decoy ('-D') source IP addresses:
nmap -T0 -D decoy1_ipaddress,decoy2_ipaddress,...,decoyN_ipaddress address_or_addresses
