About DevRef
DevRef is a developer command reference site that helps you quickly find syntax, parameters, and practical usage for common commands.
Why This Site
During development, you often need to look up command parameters - how to use git rebase, what are the tar extraction flags, how to find which process is using a port. Official documentation is comprehensive but often takes a long time to find what you need. DevRef organizes the most common commands by scenario, providing copy-ready examples so you can find answers in seconds.
Content Sources
All command information is compiled from official documentation and practical experience. Content is regularly updated to reflect the latest tool versions. If you find errors or outdated information, please provide feedback through the contact page.
