+        在畫面的中下方的區塊是終端機，你可以在終端機裡輸入指令來操作電腦。
+        在終端機中，你所看到的 `commander:~ $` 叫做命令提示字串。
+        命令提示字串最後的錢字號 `$` 叫命令提示符，你必須將指令輸入在它的後方。
+        當你輸入完指令並按下 Enter 之後，終端機會執行你輸入的指令，並且會從終端機的下一行開始輸出指令的執行結果。
+        直到你看到新的 `commander:~ $` 出現時，代表你可以輸入下一個指令了。
+        現在請你輸入 `echo hello` 來看看會發生什麼事。
+      hint: |
+        在 `commander:~ $` 後面輸入 `echo hello` 並按下 Enter

+        你應該可以看到終端機上顯示了以下內容：
+        ```
+        commander:~ $ echo hello
+        hello
+        ```
+        第一行的 `commander:~ $` 是命令提示字串，接在後方的 `echo hello` 是你輸入的指令。
+        第二行的 `hello` 則是終端機的輸出結果。
+        你現在知道了如何在終端機上輸入指令，以及查看終端機輸出的位置。
+        現在請輸入 `echo next` 來繼續下一個步驟。
+      hint: |
+        輸入 `echo next` 繼續下一個步驟

+  - id: echo-next

+    condition:
+      command: ^echo next$
+    response:
+      content: |
+        `Ctrl + C` 在終端機中是一個很重要的快捷鍵，它可以用來中斷正在執行的指令，並產生一個新的命令提示字串，讓你可以繼續輸入指令。
+        如果指令執行很久沒有反應，或你因為其他原因想要中斷指令，你可以按下 `Ctrl + C` 來中斷指令。
+        又或者你輸入了錯誤的指令，卻懶得慢慢刪除，你也可以按下 `Ctrl + C` 來產生新的命令提示字串重新輸入指令。
+        如果你已經理解了剛才的說明，請輸入 `echo finish` 來結束這一關。
+      hint: |
+        按下 `Ctrl + C` 能夠中斷正在執行的指令
