+Usage:
+ epctl [--lang zh|en] [--no-color]
+ epctl zh
+ epctl en
+ epctl [--lang zh|en] menu
+ epctl [--lang zh|en] download [--tag ]
+ epctl [--lang zh|en] install [--tag ] [--app-uri URL] [--listen ADDR:PORT]

+
+Global options:
+ --lang zh|en Select the interface language
+ --no-color Disable colored output
+ Shortcut `epctl zh` enters Chinese directly; `epctl en` enters English directly
+
+Command summary:
+ menu Open the interactive menu; `epctl` with no arguments does this too
+ download Download a GitHub release archive into /tmp/epusdt//
+ install Install or refresh /opt/epusdt and register epusdt.service
+ upgrade Upgrade to a newer release while keeping the existing .env
+ self-install Install epctl into /usr/local/bin
+ show-config Print the active /opt/epusdt/.env file
+ init-password Request the initial admin password from the local HTTP route
+ status Show the systemd status of epusdt
+ logs Show recent service logs
+
+Notes:
+ - Linux only
+ - Binary installation only
+ - install / upgrade / self-install write into /opt, /etc/systemd, and /usr/local/bin
+ - privileged commands automatically re-exec through sudo
+ - tags must match real GitHub release tags such as v1.0.6
+ - if --tag is omitted, epctl resolves the latest release and asks for confirmation

+# epctl Installation and Verification Scripts
+
+`epctl` is the repo-root Linux binary installer and service manager for released `epusdt` binaries on GitHub Releases.
+`epctl-docker-test.sh` is the matching end-to-end validation script. It launches Ubuntu + systemd in Docker and verifies download, install, startup, upgrade, and init-password behavior with real release artifacts.
+
+## Scope
+
+- Linux only
+- Binary installation only
+- Release source is fixed to `https://github.com/GMWalletApp/epusdt/releases`
+- Service management is based on systemd
+
+## Dependencies and Privileges
+
+`epctl` expects these commands:
+
+- `curl`
+- `tar`
+- `systemctl`
+- `install`
+- `grep`
+- `sed`
+
+Notes:
+
+- `install`, `upgrade`, and `self-install` write into `/opt`, `/etc/systemd`, and `/usr/local/bin`
+- `status` and `logs` automatically re-run through `sudo` when needed
+- in practice, the operator should have `sudo` access
+
+## Fixed Paths
+
+| Item | Path |
+|------|------|
+| Install directory | `/opt/epusdt` |
+| Main binary | `/opt/epusdt/epusdt` |
+| Active config | `/opt/epusdt/.env` |
+| Example config | `/opt/epusdt/.env.example` |
+| Extracted frontend assets | `/opt/epusdt/www` |
+| Download cache | `/tmp/epusdt//` |
+| systemd unit | `/etc/systemd/system/epusdt.service` |
+| Global epctl path | `/usr/local/bin/epctl` |
+
+## Quick Start
+
+Run the interactive menu from the repo root:
+
+```bash
+./epctl
+```
+
+The default interactive language is Chinese. You can force either language:
+
+```bash
+./epctl zh
+./epctl en
+./epctl --lang zh help
+./epctl --lang en help
+```
+
+Install the script into PATH:
+
+```bash
+./epctl self-install
+epctl
+```
+
+## Common Commands
+
+Download a specific release:
+
+```bash
+./epctl download --tag v1.0.8
+```
+
+Install the service:
+
+```bash
+./epctl install --tag v1.0.8 \
+ --app-uri https://pay.example.com \
+ --listen 127.0.0.1:18000
+```
+
+Upgrade to a newer release:
+
+```bash
+./epctl upgrade --tag v1.0.9
+```
+
+Inspect config, status, and logs:
+
+```bash
+./epctl show-config
+./epctl status
+./epctl logs --lines 200
+```
+
+Request the initial admin password:
+
+```bash
+./epctl init-password
+```
+
+## Behavior When `--tag` Is Omitted
+
+For `download`, `install`, and `upgrade`, `epctl` resolves the current latest GitHub release tag first, then shows the exact tag and asks for confirmation.
+
+Example:
+
+```bash
+./epctl install --app-uri https://pay.example.com
+```
+
+In interactive use, the script will display the resolved latest tag before continuing.
+For automation, passing `--tag` explicitly is preferred. If you intentionally want to skip the confirmation, use:
+
+```bash
+EPCTL_ASSUME_YES=1 ./epctl download
+```
+
+## What Happens on First Install
+
+`install` performs these steps:
+
+1. Detect the current CPU architecture and download the matching GitHub Release archive
+2. Extract into `/tmp/epusdt//extract/`
+3. Install the binary to `/opt/epusdt/epusdt`
+4. Install `.env.example` to `/opt/epusdt/.env.example`
+5. Create the system user and group `epusdt`
+6. Auto-create `/opt/epusdt/.env` from `.env.example` if it does not exist
+7. Write and enable `epusdt.service`
+
+When `.env` is auto-created, the script applies only the minimum bootstrap changes:
+
+- `install=false`
+- `app_uri=<--app-uri, default http://127.0.0.1:8000>`
+- `http_listen=<--listen, default 127.0.0.1:8000>`
+
+If `/opt/epusdt/.env` already exists, install and upgrade keep it unchanged.
+
+## systemd Service Details
+
+The service name is fixed to `epusdt.service` and uses these core settings:
+
+```ini
+WorkingDirectory=/opt/epusdt
+ExecStart=/opt/epusdt/epusdt http start
+User=epusdt
+Group=epusdt
+Restart=always
+RestartSec=3
+```
+
+The working directory stays at `/opt/epusdt` because the program extracts its `www/` assets next to the binary.
+
+## What `init-password` Does
+
+`epctl init-password` only calls the local HTTP route:
+
+```text
+GET /admin/api/v1/auth/init-password
+```
+
+It does not read the database directly.
+
+The script reads `http_listen` from `/opt/epusdt/.env` and normalizes these listen values into a local request target:
+
+- `:8000` -> `127.0.0.1:8000`
+- `0.0.0.0:8000` -> `127.0.0.1:8000`
+
+If the API returns `10040`, the bootstrap plaintext password is no longer available. Common reasons are:
+
+- the admin password has already been changed
+- the initial password has already been consumed and cannot be fetched again
+
+In that case, `epctl` prints the original HTTP error body for diagnosis.
+
+## Docker Validation Script
+
+The repo also provides:
+
+```bash
+./epctl-docker-test.sh [upgrade-tag]
+```
+
+Examples:
+
+```bash
+./epctl-docker-test.sh v1.0.6
+./epctl-docker-test.sh --lang en v1.0.6 v1.0.8
+```
+
+It performs these checks on the local machine:
+
+- builds an `ubuntu:24.04` + systemd test image
+- starts a privileged container
+- runs `epctl self-install` inside the container
+- downloads real GitHub Release artifacts
+- installs `epusdt`
+- verifies the systemd service, `www/index.html`, config output, logs, and status
+- verifies that `init-password` succeeds once and later returns `10040` after the admin password is changed
+
+Requirements:
+
+- Docker installed locally
+- permission to run Docker
+- outbound access to GitHub Releases
+
+## Recommendations
+
+- Prefer explicit `--tag` values in automation
+- After installation, run `./epctl show-config` once to verify the active `.env`
+- Change the admin password immediately after retrieving the initial password
+- If you want to validate the installer itself, run `./epctl-docker-test.sh` first

+# epctl 安装与验证脚本
+
+`epctl` 是仓库顶层的 Linux 二进制安装管理脚本，面向已经发布到 GitHub Releases 的 `epusdt` 二进制包。
+`epctl-docker-test.sh` 是配套的真实验收脚本，用本机 Docker 启动 Ubuntu + systemd 容器，完整验证安装、启动、升级和初始化密码流程。
+
+## 适用范围
+
+- 仅支持 Linux
+- 仅支持二进制安装
+- 安装源固定为 `https://github.com/GMWalletApp/epusdt/releases`
+- 默认通过 systemd 管理服务
+
+## 依赖与权限
+
+`epctl` 依赖这些基础命令：
+
+- `curl`
+- `tar`
+- `systemctl`
+- `install`
+- `grep`
+- `sed`
+
+其中：
+
+- `install`、`upgrade`、`self-install` 需要写入 `/opt`、`/etc/systemd`、`/usr/local/bin`
+- `status`、`logs` 会在需要时自动通过 `sudo` 重新执行
+- 所以日常使用建议当前用户具备 `sudo` 权限
+
+## 固定路径
+
+| 项目 | 路径 |
+|------|------|
+| 安装目录 | `/opt/epusdt` |
+| 主程序 | `/opt/epusdt/epusdt` |
+| 配置文件 | `/opt/epusdt/.env` |
+| 示例配置 | `/opt/epusdt/.env.example` |
+| 前端释放目录 | `/opt/epusdt/www` |
+| 下载缓存 | `/tmp/epusdt//` |
+| systemd unit | `/etc/systemd/system/epusdt.service` |
+| epctl 全局安装位置 | `/usr/local/bin/epctl` |
+
+## 快速开始
+
+直接在仓库根目录运行交互菜单：
+
+```bash
+./epctl
+```
+
+默认优先进入中文界面。你也可以显式指定语言：
+
+```bash
+./epctl zh
+./epctl en
+./epctl --lang zh help
+./epctl --lang en help
+```
+
+如果想把脚本装进 PATH：
+
+```bash
+./epctl self-install
+epctl
+```
+
+## 常用命令
+
+下载指定版本：
+
+```bash
+./epctl download --tag v1.0.8
+```
+
+安装服务：
+
+```bash
+./epctl install --tag v1.0.8 \
+ --app-uri https://pay.example.com \
+ --listen 127.0.0.1:18000
+```
+
+升级到新版本：
+
+```bash
+./epctl upgrade --tag v1.0.9
+```
+
+查看配置、状态、日志：
+
+```bash
+./epctl show-config
+./epctl status
+./epctl logs --lines 200
+```
+
+请求初始化管理员密码：
+
+```bash
+./epctl init-password
+```
+
+## 不传 `--tag` 时的行为
+
+`download`、`install`、`upgrade` 在未传 `--tag` 时，会先调用 GitHub API 解析当前 latest release tag，再向用户显示实际 tag 并确认。
+
+例如：
+
+```bash
+./epctl install --app-uri https://pay.example.com
+```
+
+交互模式下会先提示检测到的最新 tag。
+非交互脚本执行时，建议显式传入 `--tag`。如果你明确要跳过确认，可以设置：
+
+```bash
+EPCTL_ASSUME_YES=1 ./epctl download
+```
+
+## 首次安装时会发生什么
+
+执行 `install` 时，脚本会：
+
+1. 按当前机器架构下载 GitHub Release 压缩包
+2. 解压到 `/tmp/epusdt//extract/`
+3. 安装二进制到 `/opt/epusdt/epusdt`
+4. 安装 `.env.example` 到 `/opt/epusdt/.env.example`
+5. 创建系统用户和组 `epusdt`
+6. 若 `/opt/epusdt/.env` 不存在，则从 `.env.example` 自动生成
+7. 写入并启用 `epusdt.service`
+
+自动生成 `.env` 时，脚本只会补默认上线所需的最小改动：
+
+- `install=false`
+- `app_uri=<--app-uri，默认 http://127.0.0.1:8000>`
+- `http_listen=<--listen，默认 127.0.0.1:8000>`
+
+如果 `/opt/epusdt/.env` 已存在，则安装和升级都会保留它，不会覆盖。
+
+## systemd 服务说明
+
+脚本注册的服务名固定为 `epusdt.service`，核心参数如下：
+
+```ini
+WorkingDirectory=/opt/epusdt
+ExecStart=/opt/epusdt/epusdt http start
+User=epusdt
+Group=epusdt
+Restart=always
+RestartSec=3
+```
+
+`WorkingDirectory` 固定为 `/opt/epusdt`，因为程序会在二进制同级目录释放 `www/` 静态文件。
+
+## `init-password` 的含义
+
+`epctl init-password` 只会请求本地 HTTP 路由：
+
+```text
+GET /admin/api/v1/auth/init-password
+```
+
+它不会直接读数据库。
+
+脚本会从 `/opt/epusdt/.env` 解析 `http_listen`，然后自动把这些监听写法转成本地可请求地址：
+
+- `:8000` -> `127.0.0.1:8000`
+- `0.0.0.0:8000` -> `127.0.0.1:8000`
+
+如果接口返回 `10040`，含义是初始化明文密码已经不可用。常见原因是：
+
+- 管理员已经登录并修改过密码
+- 初始化密码已经被消费，当前不再允许再次取回
+
+此时脚本会直接把接口原始错误输出出来，方便排查。
+
+## Docker 验收脚本
+
+仓库顶层提供：
+
+```bash
+./epctl-docker-test.sh [upgrade-tag]
+```
+
+示例：
+
+```bash
+./epctl-docker-test.sh v1.0.6
+./epctl-docker-test.sh --lang zh v1.0.6 v1.0.8
+```
+
+它会在本机：
+
+- 构建 `ubuntu:24.04` + systemd 测试镜像
+- 启动一个特权容器
+- 在容器内执行 `epctl self-install`
+- 下载真实 GitHub Release
+- 安装 `epusdt`
+- 检查 `systemd` 服务、`www/index.html`、配置文件、日志、状态输出
+- 验证 `init-password` 首次成功、修改管理员密码后再次请求返回 `10040`
+
+运行前提：
+
+- 本机已安装 Docker
+- 当前用户有权限执行 Docker
+- 宿主机能够访问 GitHub Releases
+
+## 建议
+
+- 自动化部署场景优先显式传 `--tag`

+- 首次拿到初始化密码后，建议立即登录后台修改管理员密码
+- 如果只是验证脚本是否可用，优先跑 `./epctl-docker-test.sh`
