是否有一種在 Bash 中實現測驗的好方法，每次問題都是隨機的，並且記錄用戶的不同反應（正確、錯誤、通過），然後在測驗結束時給出？
我想數組可以用來存儲測驗問題和答案，測驗問題本身可以在一段時間內或直到循環內提出，並且可以遞增各種問題直到到達最後一個問題，然後可以評估用戶的表現通過使用各種條件語句？
請注意這個老問題討論了圖形測驗軟體並明確提到了聲音/圖形等，而我僅討論基於命令列文字的測驗。
（我已經在下面回答了我自己的問題......但是如果有人有另一個 Bash 測驗框架，請發布。）
答案1
我提出的測驗框架發佈在下面，也發佈在GitHub（原始使用者 GitHub 頁面已不存在）。
由於它看起來相當複雜，我最好解釋一下它是如何工作的。
在腳本中，迄今為止所有發行版的 Ubuntu 版本和代號都儲存在兩個陣列中。然後變數被初始化外部直到循環，因此它們可以根據需要在循環中使用 C 樣式(( var++ ))表示法遞增。
然後，我為問題編號建立另一個數組，在本例中，對於 19 個問題，我必須包含 0 - 18（含）：
questions_order=(15 4 1 10 8 3 13 0 11 16 2 7 5 17 6 9 14 18 12)
然後使用它來打亂它shuf並創建一個新數組並將其用於該腳本的特定運行：
shuffled_order=( $(shuf -n19 -e ${questions_order[@]}) )
這必須完成外部循環的，因為我只希望它執行一次。
簡而言之，現在循環運行直到當前問題數等於變量"${target_questions}"，然後給出結果。
當用戶對問題做出回答時，它將由case聲明中的各種條件進行解釋。無答案（空白）、錯誤答案、正確答案和通過都被檢測到並接收響應，並且各種變量都被遞增（例如，對於錯誤答案，(( wrong++ ))）。
當回答最後一個問題後，將評估使用者的表現，其中正確、錯誤答案和通過次數（如果有）會被轉發，並且還會給出所花費的時間。
這是一個簡短的解釋，但腳本本身有各種註釋，應該會使工作原理清晰（ish）！它可以適用於任何其他類型的測驗，例如關於首都和國家的測驗。
將腳本複製到檔案中後，使其可執行 ( chmod u+x)，然後運行它./scriptname或將其放入資料夾中~/bin，並像任何其他程式一樣按名稱呼叫它，假設您的檔案~/bin位於PATH.
