编辑.txt文件与批处理文件 [英] Editing a .txt file with a batch file

问题描述

好吧，我环顾四周，并试图去适应一些code我确实发现，使其工作，但我已经尝试了所有尝试都失败的。

基本上我有一个文本文件，我们会打电话给它的test.txt

TEXT.TXT包含以下三行：

  VAR1 = TEST1
VAR2 = TEST2
VAR3 = TEST3
 

基本上我试图让一个批处理文件来问我什么，我想VAR3的值更改为，然后更改VAR3的值，以反映我在键入

这可能吗？如果是的话我将如何做到这一点？

解决方案

@ECHO OFF
SETLOCAL
FOR %%一个在（var2change var2change2）DO SET一%% =
SET / p var2change =更改哪些变量？
SET / p var2change2 =更改％var2change％至？
ECHO前值
TYPE q24373191.txt
ECHO =============
::做出临时文件
：maketemp
SET临时文件=％TEMP％\\％随机％
如果不存在％临时文件％*（GOTO maketemp）ELSE（ECHO方式＆gt;％临时文件％A）（
FOR / F令牌= 1 * delims ==%%一个IN（'型q24373191.txt'）DO（
 IF / I%%一个==％var2change％（ECHO %% A =％var2change2％
 ）ELSE（ECHO %% A = %% b
 ）
）
）＆gt;中％临时文件％了COPY / Y / B％临时文件％一个q24373191.txt＆GT; NUL
DEL％临时文件％了ECHO值后
TYPE q24373191.txtGOTO：EOF


我用命名包含您的数据，我的测试文件 q24373191.txt 。

Alright, I've looked around and tried to adapt some of the code I did find to make it work but all attempts I've tried have failed.

Basically I have a text file, we'll call it TEST.txt

TEXT.txt contains these three lines:

Var1=test1
Var2=test2
Var3=test3

Basically I am trying to get a batch file to ask me what I want to change the value of var3 to and then change the value of var3 to reflect what I typed in.

Is this possible? If so how would I accomplish this?

解决方案

@ECHO OFF
SETLOCAL
FOR %%a iN (var2change var2change2) DO SET "%%a="
SET /p var2change="Change which variable ? "
SET /p var2change2="Change %var2change% to ? "


ECHO Values before
TYPE q24373191.txt
ECHO =============
:: make a tempfile
:maketemp
SET "tempfile=%temp%\%random%"
IF EXIST "%tempfile%*" (GOTO maketemp) ELSE (ECHO.>"%tempfile%a")

(
FOR /f "tokens=1*delims==" %%a IN ('type q24373191.txt') DO (
 IF /i "%%a"=="%var2change%" (ECHO %%a=%var2change2%
 ) ELSE (ECHO %%a=%%b
 )
)
)>"%tempfile%a"

COPY /y /b "%tempfile%a" q24373191.txt >nul
DEL "%tempfile%a"

ECHO Values after
TYPE q24373191.txt

GOTO :EOF

I used a file named q24373191.txt containing your data for my testing.
