x-cmd
A modern toolkit for POSIX shell that provides a standard library of modules and an on-demand package system, optimized for AI agents.
What is x-cmd?
X-CMD is a modern toolkit for POSIX shells (bash, zsh, ash, dash) that functions as a standard library, enhancing shell capabilities with over 300 modules written in shell/awk. It solves the problem of fragmented and hard-to-manage CLI tools by providing a unified command (`x`) to access both its native modules and a curated collection of 600+ on-demand third-party packages, all while prioritizing extreme portability and AI-native workflows.
Shell power users, system administrators, and developers working in POSIX environments, especially those managing multiple systems, containers, or minimal distributions like BusyBox and Alpine. It is also specifically optimized for developers and engineers building or utilizing AI agents that interact with the command line.
Developers choose X-CMD for its unique combination of a portable, POSIX-native standard library and a lightweight, on-demand package manager that requires no root access and avoids system pollution. Its core differentiator is being optimized for the AI agent era, providing pure-shell access to multiple AI providers and a design philosophy that leverages shell's flexibility and AWK streaming for agent workflows.
