x-cmd

X‑CMD provides a modern toolkit that turns any POSIX‑compatible shell into a rich programming environment similar to Python’s standard library. It ships with more than three hundred shell‑ and awk‑based modules that add capabilities such as cross‑shell theming, advanced completions, Git hook management, calendar utilities, and WeChat integration, all usable with a simple `x <module>` command.

In addition to the library, X‑CMD offers an on‑demand package system that supplies over six hundred curated command‑line tools—including jq, fzf, fd, ripgrep, node, and python—without requiring root privileges or system‑wide installation. Packages are lightweight, download on demand, and load in milliseconds, keeping the core footprint around 1 MB.

The toolkit also includes native AI support: a pure‑shell agent can call OpenAI, Gemini, DeepSeek, Zhipu, and MiniMax via curl, enabling AI agents to orchestrate thousands of commands. Installation works in bash, zsh, dash, and ash through a single curl or wget script, making X‑CMD suitable for Linux, macOS, Windows, and BSD environments.
