Duf guide

Open CLI packages the install path, verify step, and safe-start workflow so this tool can move from “interesting CLI” to something you can actually use. It also integrates with skills.sh so each CLI comes with the right companion skills, not just a binary and a docs link.

When to apply

  • disk free, filesystem status, and readable df from the terminal.
  • You work with observability and want a fast terminal interface.
  • You need disk free.
  • You need filesystem status.
  • You need readable df.
