-### Setting up a SSH Key
+---
 
-Make sure to follow the below steps while creating SSH Keys and using them.
-The best practice is create the SSH Keys on local machine not remote machine.
-Login with username specified in Github Secrets. Generate a RSA Key-Pair:
+## 🔑 SSH Key Setup & OpenSSH Compatibility
 
-### Generate rsa key
+### Setting Up SSH Keys
+
+It is best practice to create SSH keys on your local machine (not on a remote server). Log in with the username specified in GitHub Secrets and generate a key pair:
+
+#### Generate RSA key
 
 ```bash
 ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
 ```
 
-### Generate ed25519 key
+#### Generate ED25519 key
 
 ```bash
 ssh-keygen -t ed25519 -a 200 -C "your_email@example.com"
 ```
 
-Add newly generated key into Authorized keys. Read more about authorized keys [here](https://www.ssh.com/ssh/authorized_keys/).
-
-### Add rsa key into Authorized keys
+Add the new public key to the authorized keys on your server. [Learn more about authorized keys.](https://www.ssh.com/ssh/authorized_keys/)
 
 ```bash
-cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
+# Add RSA key
+cat .ssh/id_rsa.pub | ssh user@host 'cat >> .ssh/authorized_keys'
+
+# Add ED25519 key
+cat .ssh/id_ed25519.pub | ssh user@host 'cat >> .ssh/authorized_keys'
 ```
 
-### Add ed25519 key into Authorized keys
+Copy the private key content and paste it into GitHub Secrets.
 
 ```bash
-cat .ssh/id_ed25519.pub | ssh b@B 'cat >> .ssh/authorized_keys'
+# macOS
+pbcopy < ~/.ssh/id_rsa
+# Ubuntu
+xclip < ~/.ssh/id_rsa
 ```
 
-Copy Private Key content and paste in Github Secrets.
+> **Tip:** Copy from `-----BEGIN OPENSSH PRIVATE KEY-----` to `-----END OPENSSH PRIVATE KEY-----` (inclusive).
 
-### Copy rsa Private key
+For ED25519:
 
 ```bash
-clip < ~/.ssh/id_rsa
+# macOS
+pbcopy < ~/.ssh/id_ed25519
+# Ubuntu
+xclip < ~/.ssh/id_ed25519
 ```
 
-### Copy ed25519 Private key
+See more: [SSH login without a password](http://www.linuxproblem.org/art_9.html).
 
-```bash
-clip < ~/.ssh/id_ed25519
-```
+> **Note:** Depending on your SSH version, you may also need to:
+>
+> - Place the public key in `.ssh/authorized_keys2`
+> - Set `.ssh` permissions to 700
+> - Set `.ssh/authorized_keys2` permissions to 640
 
-See the detail information about [SSH login without password](http://www.linuxproblem.org/art_9.html).
+### OpenSSH Compatibility
 
-**A note** from one of our readers: Depending on your version of SSH you might also have to do the following changes:
-
-* Put the public key in `.ssh/authorized_keys2`
-* Change the permissions of `.ssh` to 700
-* Change the permissions of `.ssh/authorized_keys2` to 640
-
-### If you are using OpenSSH
-
-If you are currently using OpenSSH and are getting the following error:
+If you see this error:
 
 ```bash
 ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey]
 ```
 
-Make sure that your key algorithm of choice is supported. On Ubuntu 20.04 or later you must explicitly allow the use of the ssh-rsa algorithm. Add the following line to your OpenSSH daemon file (which is either `/etc/ssh/sshd_config` or a drop-in file under `/etc/ssh/sshd_config.d/`):
+On Ubuntu 20.04+ you may need to explicitly allow the `ssh-rsa` algorithm. Add this to your OpenSSH daemon config (`/etc/ssh/sshd_config` or a drop-in under `/etc/ssh/sshd_config.d/`):
 
 ```bash
 CASignatureAlgorithms +ssh-rsa
 ```
 
-Alternatively, `ed25519` keys are accepted by default in OpenSSH. You could use this instead of rsa if needed:
+Alternatively, use ED25519 keys (supported by default):
 
 ```bash
 ssh-keygen -t ed25519 -a 200 -C "your_email@example.com"
 ```

-It is not uncommon for files to leak from backups or decommissioned hardware, and hackers commonly exfiltrate files from compromised systems.
+## 🛡️ Security Best Practices

-#### Using host fingerprint verification
+### Host Fingerprint Verification
 
-Setting up SSH host fingerprint verification can help to prevent Person-in-the-Middle attacks. Before setting this up, run the command below to get your SSH host fingerprint. Remember to replace `ed25519` with your appropriate key type (`rsa`, `dsa`, etc.) that your server is using and `example.com` with your host.
-
-In modern OpenSSH releases, the _default_ key types to be fetched are `rsa` (since version 5.1), `ecdsa` (since version 6.0), and `ed25519` (since version 6.7).
+Verifying the SSH host fingerprint helps prevent man-in-the-middle attacks. To get your host's fingerprint (replace `ed25519` with your key type and `example.com` with your host):
 
 ```sh
 ssh example.com ssh-keygen -l -f /etc/ssh/ssh_host_ed25519_key.pub | cut -d ' ' -f2

+
+## 🔑 SSH 密钥配置与 OpenSSH 兼容性
+
+### 配置 SSH 密钥
+
+建议在本地机器（而非远程服务器）上创建 SSH 密钥。请使用 GitHub Secrets 中指定的用户名登录并生成密钥对：
+
+#### 生成 RSA 密钥
+
+```bash
+ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
+```
+
+#### 生成 ED25519 密钥
+
+```bash
+ssh-keygen -t ed25519 -a 200 -C "your_email@example.com"
+```
+
+将新生成的公钥添加到服务器的 authorized_keys。 [了解更多 authorized_keys](https://www.ssh.com/ssh/authorized_keys/)
+
+```bash
+# 添加 RSA 公钥
+cat .ssh/id_rsa.pub | ssh user@host 'cat >> .ssh/authorized_keys'
+
+# 添加 ED25519 公钥
+cat .ssh/id_ed25519.pub | ssh user@host 'cat >> .ssh/authorized_keys'
+```
+
+复制私钥内容并粘贴到 GitHub Secrets。
+
+```bash
+# macOS
+pbcopy < ~/.ssh/id_rsa
+# Ubuntu
+xclip < ~/.ssh/id_rsa
+```
+
+> **提示：** 复制内容需包含 `-----BEGIN OPENSSH PRIVATE KEY-----` 到 `-----END OPENSSH PRIVATE KEY-----`（含）。
+
+ED25519 同理：
+
+```bash
+# macOS
+pbcopy < ~/.ssh/id_ed25519
+# Ubuntu
+xclip < ~/.ssh/id_ed25519
+```
+
+更多信息：[SSH 无密码登录](http://www.linuxproblem.org/art_9.html)。
+
+> **注意：** 根据 SSH 版本，可能还需：
+>
+> - 将公钥放入 `.ssh/authorized_keys2`
+> - 设置 `.ssh` 权限为 700
+> - 设置 `.ssh/authorized_keys2` 权限为 640
+
+### OpenSSH 兼容性
+
+如果出现如下错误：
+
+```bash
+ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey]
+```
+
+在 Ubuntu 20.04+，你可能需要显式允许 `ssh-rsa` 算法。请在 OpenSSH 配置文件（`/etc/ssh/sshd_config` 或 `/etc/ssh/sshd_config.d/` 下的 drop-in 文件）中添加：
+
+```bash
+CASignatureAlgorithms +ssh-rsa
+```
+
+或者，直接使用默认支持的 ED25519 密钥：
+
+```bash
+ssh-keygen -t ed25519 -a 200 -C "your_email@example.com"
+```
+

+    key: ${{ secrets.KEY }}
+    port: ${{ secrets.PORT }}
+    script: |
+      whoami
+      ls -al
+```
+
+![result](./images/output-result.png)
+
+### 从文件执行命令
+
+```yaml
+- name: 文件命令
+  uses: appleboy/ssh-action@v1
+  with:
+    host: ${{ secrets.HOST }}
+    username: ${{ secrets.USERNAME }}
+    key: ${{ secrets.KEY }}
+    port: ${{ secrets.PORT }}
+    script_path: scripts/script.sh
+```
+
+### 多主机
+
+```diff
+  - name: 多主机
+    uses: appleboy/ssh-action@v1
+    with:
+-     host: "foo.com"
++     host: "foo.com,bar.com"
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      port: ${{ secrets.PORT }}
+      script: |
+        whoami
+        ls -al
+```
+
+默认 `port` 为 `22`。
+
+### 多主机不同端口
+
+```diff
+  - name: 多主机
+    uses: appleboy/ssh-action@v1
+    with:
+-     host: "foo.com"
++     host: "foo.com:1234,bar.com:5678"
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      script: |
+        whoami
+        ls -al
+```
+
+### 多主机同步执行
+
+```diff
+  - name: 多主机
+    uses: appleboy/ssh-action@v1
+    with:
+      host: "foo.com,bar.com"
++     sync: true
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      port: ${{ secrets.PORT }}
+      script: |
+        whoami
+        ls -al
+```
+
+### 传递环境变量到 shell 脚本
+
+```diff
+  - name: 传递环境变量
+    uses: appleboy/ssh-action@v1
++   env:
++     FOO: "BAR"
++     BAR: "FOO"
++     SHA: ${{ github.sha }}
+    with:
+      host: ${{ secrets.HOST }}
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      port: ${{ secrets.PORT }}
++     envs: FOO,BAR,SHA
+      script: |
+        echo "I am $FOO"
+        echo "I am $BAR"
+        echo "sha: $SHA"
+```
+
+> _`env` 对象中的所有环境变量必须为字符串。传递整数或其他类型可能导致意外结果。_
+
+---
+
+## 🌐 代理与跳板机用法
+
+你可以通过代理（跳板机）连接到远程主机，适用于进阶网络拓扑。
+
+```bash
++--------+       +----------+      +-----------+
+| Laptop | <-->  | Jumphost | <--> | FooServer |
++--------+       +----------+      +-----------+
+```
+
+示例 `~/.ssh/config`：
+
+```bash
+Host Jumphost
+  HostName Jumphost
+  User ubuntu
+  Port 22
+  IdentityFile ~/.ssh/keys/jump_host.pem
+
+Host FooServer
+  HostName FooServer
+  User ubuntu
+  Port 22
+  ProxyCommand ssh -q -W %h:%p Jumphost
+```
+
+**GitHub Actions YAML:**
+
+```diff
+  - name: SSH 代理命令
+    uses: appleboy/ssh-action@v1
+    with:
+      host: ${{ secrets.HOST }}
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      port: ${{ secrets.PORT }}
++     proxy_host: ${{ secrets.PROXY_HOST }}
++     proxy_username: ${{ secrets.PROXY_USERNAME }}
++     proxy_key: ${{ secrets.PROXY_KEY }}
++     proxy_port: ${{ secrets.PROXY_PORT }}
+      script: |
+        mkdir abc/def
+        ls -al
+```
+
+---
+
+## 🛡️ 安全最佳实践
+
+### 保护你的私钥
+
+密码短语会加密你的私钥，即使泄露也无法被攻击者直接利用。请务必妥善保管私钥。
+
+```diff
+  - name: SSH 密钥密码短语
+    uses: appleboy/ssh-action@v1
+    with:
+      host: ${{ secrets.HOST }}
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      port: ${{ secrets.PORT }}
++     passphrase: ${{ secrets.PASSPHRASE }}
+      script: |
+        whoami
+        ls -al
+```
+
+### 主机指纹验证
+
+验证 SSH 主机指纹有助于防止中间人攻击。获取主机指纹（将 `ed25519` 替换为你的密钥类型，`example.com` 替换为你的主机）：
+
+```sh
+ssh example.com ssh-keygen -l -f /etc/ssh/ssh_host_ed25519_key.pub | cut -d ' ' -f2
+```
+
+更新配置：
+
+```diff
+  - name: SSH 密钥密码短语
+    uses: appleboy/ssh-action@v1
+    with:
+      host: ${{ secrets.HOST }}
+      username: ${{ secrets.USERNAME }}
+      key: ${{ secrets.KEY }}
+      port: ${{ secrets.PORT }}
++     fingerprint: ${{ secrets.FINGERPRINT }}
+      script: |
+        whoami
+        ls -al
+```
+

+
+## 🚨 错误处理与疑难解答
+
+### 常见问题
+
+#### 命令未找到（npm 或其他命令）
+
+如果遇到 "command not found" 错误，请参考 [此评论](https://github.com/appleboy/ssh-action/issues/31#issuecomment-1006565847) 了解交互式与非交互式 shell 的区别。
+
+许多 Linux 发行版的 `/etc/bash.bashrc` 包含如下内容：
+
+```sh
+# If not running interactively, don't do anything
+[ -z "$PS1" ] && return
+```
+
+注释掉该行或使用命令的绝对路径。

-### 設置 SSH 金鑰
+---
 
-請在創建 SSH 金鑰並使用 SSH 金鑰時遵循以下步驟。最佳做法是在本地機器上創建 SSH 金鑰而不是遠端機器上。請使用 Github Secrets 中指定的用戶名登錄。生成 RSA 金鑰：
+## 🔑 SSH 金鑰設定與 OpenSSH 相容性
 
-### 生成 RSA 金鑰
+### 設定 SSH 金鑰
+
+建議於本地端（非遠端伺服器）產生 SSH 金鑰。請以 GitHub Secrets 指定的使用者名稱登入並產生金鑰對：
+
+#### 產生 RSA 金鑰
 
 ```bash
 ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
 ```
 
-### 生成 ed25519 金鑰
+#### 產生 ED25519 金鑰
 
 ```bash
 ssh-keygen -t ed25519 -a 200 -C "your_email@example.com"
 ```
 
-將新生成的金鑰添加到已授權的金鑰中。詳細了解已授權的金鑰請點擊[此處](https://www.ssh.com/ssh/authorized_keys/).
-
-### 將 RSA 金鑰添加到已授權金鑰中
+將新產生的公鑰加入伺服器的 authorized_keys。 [了解更多 authorized_keys](https://www.ssh.com/ssh/authorized_keys/)
 
 ```bash
-cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
+# 加入 RSA 公鑰
+cat .ssh/id_rsa.pub | ssh user@host 'cat >> .ssh/authorized_keys'
+
+# 加入 ED25519 公鑰
+cat .ssh/id_ed25519.pub | ssh user@host 'cat >> .ssh/authorized_keys'
 ```
 
-### 將 ed25519 金鑰添加到已授權金鑰中
+複製私鑰內容並貼到 GitHub Secrets。
 
 ```bash
-cat .ssh/id_ed25519.pub | ssh b@B 'cat >> .ssh/authorized_keys'
+# macOS
+pbcopy < ~/.ssh/id_rsa
+# Ubuntu
+xclip < ~/.ssh/id_rsa
 ```
 
-複製私鑰內容，然後將其粘貼到 Github Secrets 中。
+> **提示：** 複製內容需包含 `-----BEGIN OPENSSH PRIVATE KEY-----` 到 `-----END OPENSSH PRIVATE KEY-----`（含）。
 
-### 複製 rsa 私鑰內容
+ED25519 同理：
 
 ```bash
-clip < ~/.ssh/id_rsa
+# macOS
+pbcopy < ~/.ssh/id_ed25519
+# Ubuntu
+xclip < ~/.ssh/id_ed25519
 ```
 
-### 複製 ed25519 私鑰內容
+更多資訊：[SSH 免密碼登入](http://www.linuxproblem.org/art_9.html)。
 
-```bash
-clip < ~/.ssh/id_ed25519
-```
+> **注意：** 根據 SSH 版本，可能還需：
+>
+> - 將公鑰放入 `.ssh/authorized_keys2`
+> - 設定 `.ssh` 權限為 700
+> - 設定 `.ssh/authorized_keys2` 權限為 640
 
-有關無需密碼登錄 SSH 的詳細信息，請[參見該網站](http://www.linuxproblem.org/art_9.html)。
+### OpenSSH 相容性
 
-**來自讀者的注意事項**： 根據您的 SSH 版本，您可能還需要進行以下更改：
-
-* 將公鑰放在 `.ssh/authorized_keys2` 中
-* 將 `.ssh` 的權限更改為700
-* 將 `.ssh/authorized_keys2` 的權限更改為640
-
-### 如果你使用的是 OpenSSH
-
-如果您正在使用 OpenSSH，並出現以下錯誤：
+若出現以下錯誤：
 
 ```bash
 ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey]
 ```
 
-請確保您所選擇的密鑰演算法得到支援。在 Ubuntu 20.04 或更高版本上，您必須明確允許使用 SSH-RSA 演算法。請在 OpenSSH 守護進程文件中添加以下行（它可以是 `/etc/ssh/sshd_config` 或 `/etc/ssh/sshd_config.d/` 中的一個附著文件）：
+在 Ubuntu 20.04+，你可能需明確允許 `ssh-rsa` 演算法。請於 OpenSSH 設定檔（`/etc/ssh/sshd_config` 或 `/etc/ssh/sshd_config.d/` 下的 drop-in 檔案）加入：
 
 ```bash
 CASignatureAlgorithms +ssh-rsa
 ```
 
-或者，`Ed25519` 密鑰在 OpenSSH 中默認被接受。如果需要，您可以使用它來替代 RSA。
+或直接使用預設支援的 ED25519 金鑰：
 
 ```bash
 ssh-keygen -t ed25519 -a 200 -C "your_email@example.com"
 ```

-#### 如何保護私鑰？
+---
 
-密碼短語通常用於加密私鑰。這使得攻擊者無法單獨使用密鑰文件。文件泄露可能來自備份或停用的硬件，黑客通常可以從受攻擊系統中洩露文件。因此，保護私鑰非常重要。
+## 🛡️ 安全最佳實踐
+
+### 保護你的私鑰
+
+密碼短語會加密你的私鑰，即使外洩也無法被攻擊者直接利用。請務必妥善保管私鑰。

+### 主機指紋驗證
 
-設置 SSH 主機指紋驗證可以幫助防止中間人攻擊。在設置之前，運行以下命令以獲取 SSH 主機指紋。請記得將 `ed25519` 替換為您的適當金鑰類型（`rsa`、 `dsa`等），而 `example.com` 則替換為您的主機。
-
-現代 OpenSSH 版本中，需要提取的_默認金鑰_類型是 `rsa`（從版本 5.1 開始）、`ecdsa`（從版本 6.0 開始）和 `ed25519`（從版本 6.7 開始）。
