 ## 二、流水线语法（超简单）
 
 - 用 `|` 连接多个操作，前一个的输出自动作为后一个的输入。
-- 用 `>` 或 `>>` 把结果保存起来（见下文）。
+- 用 `;` 分隔多条独立指令，它们各自产生输出，最终合并显示。
+- 用 `>` 或 `>>` 把结果保存起来（见下文），被重定向的指令不会产生输出。
 
-**例子**：把“HELLO”先反转，再转成摩斯电码：（转换为摩斯电码功能暂未实现）
+**例子**：把"HELLO"先反转，再转成摩斯电码：（转换为摩斯电码功能暂未实现）
 ```
 textfx reverse HELLO | morse en
 ```
 → 输出：`--- .-.. .-.. . ....`
 
+**例子**：多条指令各自输出：
+```
+textfx echo 你好; echo 世界
+```
+→ 输出：
+```
+你好
+世界
+```
+
+**例子**：重定向的指令不输出，其余正常输出：
+```
+textfx echo 1; echo 2 > a; echo 3

+```
