Disk Usage Skill

Analyzes disk space and filesystem usage on Linux systems.

Suggested Workflow

1. Run ./scripts/diskinfo.sh for a structured overview of mounts, block devices, and top directories.
2. Check df -h output for any filesystem above 80% usage.
3. Drill into high-usage mounts with du -h --max-depth=1 /mount to find large subdirectories.
4. Locate specific large files with find /path -type f -size +100M.
