For hackers, penetration testers, and security professionals, command-line one-liners are like tools in a Swiss Army knife — small, efficient, and powerful. The right command executed at the right time can reveal vulnerabilities, perform reconnaissance, or extract critical information, all with minimal effort. Here, we dive into some advanced one-liners for tasks like network scanning, file manipulation, and privilege escalation. Whether you’re an experienced pentester or a cybersecurity enthusiast, these commands can streamline your workflow and improve efficiency.

1. Network Reconnaissance and Scanning

Nmap: Discover Live Hosts in a Network

nmap -sn 192.168.1.0/24

This Nmap command performs a “ping scan” to list all live hosts on a subnet without port scanning. Adjust the IP range as needed.

Masscan: Fast Network Scanning

masscan 192.168.1.0/24 -p80,443,22 --rate=1000

Masscan is ideal for quickly identifying open ports on large networks. Specify --rate to control the scan speed.
