# X-CMD

> X-CMD is a POSIX shell toolkit: 333+ modules, 500+ portable packages, 1200+ software installation recipes.

## 1. Installation & Setup

### Installation

**Quick install (Linux/macOS/BSD/Windows WSL/GitBash, bash/zsh):**
- curl: `eval "$(curl https://get.x-cmd.com)"`
- wget: `eval "$(wget -O- https://get.x-cmd.com)"`

**Non-POSIX shells (Fish, Elvish, Nushell, xonsh, tcsh):**
- Fish docs: https://x-cmd.com/start/fish.md
- Elvish docs: https://x-cmd.com/start/elvish.md
- Nushell docs: https://x-cmd.com/start/nushell.md
- xonsh docs: https://x-cmd.com/start/xonsh.md
- tcsh docs: https://x-cmd.com/start/tcsh.md

**System package managers:**
- Homebrew: `brew install x-cmd`, then run `x-cmd` to activate
- AUR: `sudo yay -S x-cmd`, then run `x-cmd` to activate

**Windows PowerShell:**
- PowerShell docs: https://x-cmd.com/start/powershell.md

**Docker containers (minimal environments without curl/wget):**
- From host: `x docker run -x -it <container>` or `x docker setup <container>`

**Verify installation**: check `~/.x-cmd.root/X` and `~/.x-cmd.root/bin/x-cmd` exist.
**Update**: `x upgrade` or re-run the install script.
**Uninstall**: `x uninstall self`

### Loading & Fallback

1.  **Load**: Before using `x` commands, run:
    ```sh
    [ -f ~/.x-cmd.root/X ] || eval "$(curl https://get.x-cmd.com)"
    . ~/.x-cmd.root/X
    ```
2.  **Fallback**: If `x` is not available (non-persistent shell session), use standalone command `x-cmd <module> [args]` (located at `~/.x-cmd.root/bin/x-cmd`, no shell function loading required).
3.  **Final Fallback**: If `x-cmd` is also not found, use absolute path: `~/.x-cmd.root/bin/x-cmd <module> [args]`

## 2. AI Usage Rules

- **Tool Availability**: `x <tool>` (e.g., `x jq`, `x python`) auto-detects whether the tool is installed; if missing, silently installs a portable version. Use when you need to ensure a tool is available.
- **Enhanced Modules**: Some modules provide enhanced functionality and behave differently from native commands (e.g., `x docker` ≠ `docker`, provides metadata extraction and status monitoring). Run `x <module> --help` before use.
- **Structured Output**: `x` modules output TSV, JSON, or `key: value` formats in pipe mode. Prefer `--json` flag when available.
- **No TTY Constraint**: DO NOT run interactive/TUI app commands in AI environments.

## 3. X-CMD Architecture

### Module Types

X-CMD functionality is organized as logical modules in two categories:

1. **Command Enhancement Wrappers**: `x id`, `x uname`, `x df`, `x docker`, etc. enhance native system commands.
   - TTY mode: Interactive TUI or colored structured output for human reading.
   - Pipe mode: Structured data output (TSV or JSON) for program/AI parsing.
   - Note: Enhanced modules (e.g., `x docker`) behave differently from native commands — not drop-in replacements.

2. **Shell Function Modules**: `x str` (string manipulation), `x tldr` (documentation browser), `x ccal` (Chinese calendar), etc. provide functionality not available natively.

### Smart Detection (e.g., `x jq`)

- System already has jq installed → uses the existing version directly.
- System has no jq → automatically downloads a portable version via `x snap jq` and runs it.
- For AI: just call `x jq` uniformly — no need to worry about whether the tool is pre-installed.

### Package System (`x env`)

X-CMD manages a portable package system with static/dynamic linked packages, no root privileges required, no impact on system environment.

Three usage modes:
- `x env use jq`: Global install to user environment — `jq` command available after loading x-cmd.
- `x env try jq`: Temporary install — only available in current shell session, not retained after exit.
- `x snap jq`: On-demand download and direct execution — no environment variable changes.

Other commands: `x env ls` (view installed), `x env ll` (view all available packages), `x env unuse <pkg>` (uninstall), `x env gc` (reclaim space).

Full package list: `x env ll` or https://x-cmd.com/pkg.md

### Software Installation (`x install`)

Different systems use different package managers with different naming and syntax (apt, dnf, brew, scoop, etc.), and some software can only be installed via `curl | sh`. `x install` abstracts all these differences behind a unified alias:

- `x install docker`, `x install git` — one command, auto-selects the best install path for the current system.
- Covers 1200+ commonly used software installation recipes.

Full install recipes: `x install ll` or https://x-cmd.com/install.md

## 4. Help System

Explore usage autonomously via three levels:
1. `x --help` — View all available modules.
2. `x <module> --help` — View module functions and subcommands.
3. `x <module> <subcommand> --help` — Get TLDR examples for a specific subcommand.

## 5. Common Modules Quick Reference

> Run `x <module> --help` for details.
> All modules: `x --help` or https://x-cmd.com/mod.md
> All packages: `x env ll` or https://x-cmd.com/pkg.md

- **Data Processing**:
  - `x jq`, `x yq` — JSON/YAML/TOML processing.
  - `x csv` — Query and convert CSV/TSV data.
  - `x str` — String manipulation (Base64, URL encoding/decoding, regex replace, random string).
  - `x sed`, `x sd`, `x grep`, `x rg` — Stream editing and high-performance search.
- **System & Network**:
  - `x id`, `x df`, `x free`, `x ps`, `x stat`, `x hash` — System status and file fingerprinting (structured output in pipe mode).
  - `x ip`, `x dns`, `x ping`, `x curl`, `x ssh` — Network diagnostics, geolocation, and connection management.
- **Messaging**:
  - `x feishu`, `x dingtalk`, `x telegram`, `x discord` — Bot notification sending.
- **Runtime Environments**:
  - `x python`, `x node`, `x go`, `x bun`, `x java`, `x deno` — Runtime environment configuration.
- **DevOps & Container**:
  - `x docker` — Enhanced Docker management (note: behavior differs from native `docker`).
  - `x gh`, `x gl`, `x git` — CLI wrappers for code hosting platforms.
- **Platform & Tools**:
  - `x mac` — macOS system info and battery; `x termux` — Android environment enhancement.
  - `x zuz` — Smart decompression (auto-detects format); `x gram`, `x writer` — AI workflow orchestration.
  - `x tldr`, `x man`, `x cht` — Fast command examples and cheat sheets.

## 6. AI Skills

X-CMD provides 200+ skills to enhance Agent context awareness:
- `x skill ll`: List all available skills or view all collected skills (https://x-cmd.com/ai.md).
- `x skill suggest`: Get recommendations based on the current directory (useful during project setup or tool selection).
- `x skill add <skill-id>`: Activate a specific skill.
- `x agent setup`: Install x-cmd prompts and skills into the current Agent.

## 7. Error Recovery

- If a command fails, run `x <module> --help` to verify correct usage.
- If a module is not found, run `x --help` to search available modules.
- If a package download times out, retry once or use `x install <pkg>` to try via system package manager.
