Question

我正在尝试搜索文本文件，但我遇到了问题：

Test.txt的：

Pizza|Cheese
Filet Mignon|Meat
Bread|Dough

如何使用“for / f”命令查看所有行，然后回显一件事。这就是我现在所处的位置：

for /f "tokens=2*delims=|" %a in (test.txt) do echo %a

这回声奶酪，肉和面团。如何隔离线条，以便/ f在这些线条中查看，而不是其他线条。

这就是我想要做的事情：

@echo off
set /p Quest="What do you want to eat? "
for /f "tokens=2*delims=|" %a in (test.txt) do (
if Quest=Pizza echo ???         <===This is the area where I am having problems
if Quest="Filet mignon" echo ??? <=What are the commands so I can echo only Cheesy, Meaty, or Dough?
if Quest=Bread echo ???        <===Because what is happening right now is that everything is displayed.
)

Answer 1

您忘记了变量所需的%。我想这就是你想要的：

@echo off
set /p Quest="What do you want to eat? "
for /f "tokens=1* delims=^|" %%a in (test.txt) do if "%Quest%"=="%%~a" Echo %%b
pause

要求用户选择食品，然后回复该食品的成分。

Answer 2

我认为你打算：

@echo off
set /p Quest="What do you want to eat? "
for /f "tokens=1,2 delims=|" %%a in (test.txt) do (
  if /i "%Quest%"=="%%a" echo %%b
)
Pause

如果test.txt很大，使用FINDSTR查找所需的行会更有效：

@echo off
set /p Quest="What do you want to eat? "
for /f "tokens=2 delims=|" %%a in ('findstr /ibc:"%Quest%|" test.txt') do echo %%a
Pause

对于批处理多行中的/ f命令
