Bash script to clean up disk space for Linux

A handy interactive Bash script to inspect and optionally clean up disk space used by common development tools and system caches on Ubuntu (or any Linux system).

What it does

• Scans common dev tool folders (e.g. .npm, .yarn, .m2, .gradle, .nvm, snap, etc.) and shows their sizes.
• Prompts for deletion of each folder individually.

• Reports disk usage of:

  • APT package cache
  • journalctl system logs
  • Docker system (images, volumes, containers)

• Prompts separately before cleaning:

  • APT cache (sudo apt autoremove && apt clean)
  • Systemd journal logs (journalctl --vacuum-time=7d)
  • Docker unused data (docker system prune -a)

Features

• Simple interactive prompts for safe manual control
• Works well on local dev machines or CI runners with disk pressure
• Requires no dependencies besides standard Linux tools

Usage

Download and run:

chmod +x check-disk-usage.sh
./check-disk-usage.sh

Or run directly from Gist in one line:

bash <(curl -L https://go.khuong.dev/check-disk-usage)
