Disk & Filesystem Management (Du/Df/Lsblk/Fstrim)

Find the disk hog without waiting forever

🧩 The Challenge

Everyone has been there: you run du -sh * to find out why the server is out of space and then you just stare at a blinking cursor for ten minutes. It is agonizing when you just need to know which directory is ballooning right now.

💡 The Fix

Use the ncdu tool instead of native commands to get an interactive, sorted view of your filesystem that lets you navigate and delete files on the fly. You’ll never go back to parsing raw output again.

⚙️ Why It Works

This utility scans the disk and loads the entire structure into memory so you can browse, sort by size, and even delete files directly from the UI without having to re-run your commands.

🚀 Pro-Tip: Stick it on your troubleshooting jumpbox so you can visualize the chaos in seconds.
