如何在文本文件中找到一條線

Question

所以我在想這個，這應該就像一個說話的模擬器，如果你寫下批處理文件不知道的東西，它會要求你寫出答案對於該問題，稍後使用問題名稱創建文本文件，並在文本文件中用答案創建一行。唯一的問題是，我不知道如何讓批處理文件讀取文本文件中的行。請幫忙。

@echo off 
echo Hello! 
echo Talk To Me! 
pause>nul 
:1 
cls 
echo Enter text 
set /p talk= 
if exist %talk% (
    goto answer 
) else (
    goto dontknow 
) 
:answer 
*finds string in txt file and writes it here* 
pause>nul 
goto 1 
:dontknow 
echo I dont know that yet. Teach me what to answer 
set /p teach= 
echo %teach% >> %talk%.txt 
pause>nul 
goto 1

讀取.txt文件並將其顯示到批處理文件。使用type命令。在你的情況下，type %talk%

已編輯（次要）你的代碼如下。

@echo off 
echo Hello! 
echo Talk To Me! 
pause>nul 
:1 
cls 
echo Enter text 
set /p talk= 
if exist %~dp0%talk%.txt (
    type %talk%.txt 
    pause>nul 
    goto 1 
) else (
    goto dontknow 
) 

:dontknow 
echo I dont know that yet. Teach me what to answer 
set /p teach= 
echo %teach% >> %talk%.txt 
pause>nul 
goto 1
