Rubish: A Unix shell written in pure Ruby

SITREP: A new Unix shell named Rubish has been developed using the Ruby programming language. This shell aims to provide a Unix-like command-line interface while leveraging Ruby's features. TACTICAL ASSESSMENT: The development of Rubish indicates a growing interest in enhancing programming environments with Ruby, potentially attracting developers who prefer Ruby's syntax and capabilities. This could lead to increased adoption of Ruby in systems programming and command-line utilities. PROJECTED VECTORS: Future developments may include additional features or integrations with existing Ruby frameworks, potentially expanding its user base.
