# Disk Usage Skill

Find out what filled the disk before it stops the machine

## What this does

The disk is full, or nearly, and you need to know what is taking up the room. This looks at storage on a Linux machine and points at the biggest files and directories, how full each partition is, and whether inodes are the problem. Reach for it the moment a disk full error shows up.

### Top 3 things it does for you

- Show me what is eating my disk space
- Find the largest files and directories
- Check how full each partition is

## About Disk Usage Skill

This analyzes disk space usage, filesystem mounts, and storage allocation on Linux systems. It identifies large files and directories, checks partition usage, and reports inode consumption.

Reach for it when a disk full error appears, when you are trying to work out how much free space is left, when you are reading du or df output, or when you need to know which directories consume the most space.
