Disk Usage

Analyze disk space and find what's taking up room.

Overview

• Filesystem usage: df -h
• Current directory: du -sh .
• Subdirectory sizes: du -sh */ | sort -rh
• Top 20 largest dirs: du -h --max-depth=2 | sort -rh | head -20

Find large files

• Top 20 largest files: find . -type f -exec du -h {} + | sort -rh | head -20
• Files over 100MB: find . -size +100M -type f -exec ls -lh {} \;
• Files over 1GB: find . -size +1G -type f -exec ls -lh {} \;

Cleanup candidates

• Old log files: find /var/log -name "*.gz" -mtime +30 -type f
• Core dumps: find / -name "core.*" -type f 2>/dev/null
• Docker: docker system df (if Docker is installed)
• Package cache (apt): du -sh /var/cache/apt/archives/
