history
Project history and usage
duti is a macOS command-line utility for setting default applications for document types, URL schemes, extensions, and MIME types. It is one of those small macOS plumbing tools that became package-manager-relevant because Apple exposes the concept through Launch Services and UTIs but not through a friendly shell command.
Project history
The README says duti was originally released into the public domain by Andrew Mortensen in 2008. The current GitHub repository was created in September 2012 and hosts the README, man page, and tagged releases.
The tool is built around Apple's Uniform Type Identifiers and related handler metadata. It can read settings from stdin, a settings file, an XML plist, or command-line arguments, making it easy to script default-app policy on macOS.
Adoption history
duti's adoption is mostly in macOS automation circles: users install it through package managers or build it from source, then use it in setup scripts to make browser, editor, document, and URL-scheme defaults reproducible. The README also labels the project unsupported, which makes its persistence in package managers part of its history.
How it is used
The man page documents `duti -s` for setting handlers, `duti -x` for printing the default app for an extension, and file/plist input for bulk settings. A settings file contains bundle ID, UTI or URL scheme, and role fields such as viewer, editor, shell, all, or none.
Why package nerds care
duti matters because macOS developer machines are often rebuilt from scripts, and default application bindings are otherwise awkward to automate. It gives Homebrew/MacPorts/Nix users a small, scriptable bridge into Apple's UTI and handler database.
