Oil: The Design and Implementation of a New Unix Shell

Oil is a new open source Unix shell (http://www.oilshell.org/). The project's goal is to provide a migration path out of bash, first by defining and implementing POSIX- and bash-compatible semantics, and then by translating shell scripts to a new language.

This talk will:

• Explain the motivation for the project.
• Show demos of thousands of lines of unmodified shell scripts running under Oil.
• Explain the architecture and implementation of Oil, and how it differs from existing shells.
• Discuss open problems and future work.

Speaker Bio:

Andy Chu has been writing software in the Bay Area for 16 years -- at Google, Electronic Arts, and now independently.

He's worked on development tools, domain-specific languages, distributed systems, information retrieval, big data, privacy, and machine learning -- and used Unix shell in each of those domains.
