The Unix shell is a cornerstone of programming that has remained largely unchanged for over 50 years. The design principles of Unix, which emphasize simplicity and standard interfaces, are still relevant today. However, the software stack has expanded significantly since then, and many modern tools have built upon or replaced Unix interfaces. Dagger Shell aims to change this by introducing a new syntax frontend for the state-of-the-art runtime and composition system, the Dagger Engine. This shell provides native support for primitives like containers, secrets, and service endpoints, as well as typed objects, declarative execution, and content-addressed artifacts. It is designed to complement existing shells, rather than replace them, and offers a modern API that can be used with standard shell syntax. The goal of Dagger Shell is to simplify the process of automating software tasks, making it easier for developers to work with complex systems and reduce the need for specialized tools or DSLs.
