Description: Start learning cybersecurity with CBT Nuggets. courses.cbt.gg/security In this video, CBT Nuggets trainer Trevor Sullivan covers the easiest way to run or invoke system commands with Node-RED without hand-writing your own custom integration. The reason that Node-RED is such a popular programming tool is how easy it is to use and how versatile it is in wiring together hardware devices, APIs for various tools and integrating online services. Flow-based development is quick, easy and intuitive — especially for people who don't tend to learn programming languages regularly. It's possible to run a system command through Node-RED with hand-coded and custom integration, but it's not exactly easy, nor is it always worth the time. Instead, Trevor shows you how to use existing command line tools and just tell Node-RED to invoke them from within your script. Watch as Trevor navigates a Node-RED flow and walks you through, step-by-step, incorporating system commands. 🌩️ Download the Ultimate Cloud Cert Guide: blog.cbt.gg/kx24 ⬇️ 4-Week Study Plan: Linux+ (XK0-004): blog.cbt.gg/a8uq Start learning with CBT Nuggets: • Describe Network Switch Functions and How to Locate Network Devices | courses.cbt.gg/8s0
