『楼 主』:
怎样在dos下用批处理去修改文本文件内容
使用 LLM 解释/回答一下
我现在只知道有个findstr的命令，这个只能用来找到想要修改的字符，但是找到后用什么命令处理我就不知道了，想请教各位高手。
例如。在dos7。1英文环境下，要编辑a.txt
现在我想创建一个批处理文件，其作用是：
当发现a.txt文件中存在“a=10”这行内容的话，将10修改为0，如果发现本来“a=0"的话，则继续下面的批处理。
当发现存在“b=我”的这一行文字的话，将此行文字删除（此行文字不一定在文本的最后，可能在中间，但肯定独占一行），如不存在“b=我”的话，则添加“b=你"到a.txt（追加命令我知道“〉〉”只是想知道能否添加插入到具体位置，比如第N行）
谢谢，有劳各位费心了。
如果在纯dos下没有解决方法的话，只要能在xpsp2或98下能起到同样效果的解决方法也行。感谢
P.S.本人编程盲,也只用批处理自己做过启动盘类的小玩艺。

I now only know there is a findstr command, which can only be used to find the characters to be modified, but I don't know what command to use to process after finding. I want to ask all the experts.
For example. In the DOS 7.1 English environment, to edit a.txt
Now I want to create a batch file, whose function is:
If there is a line "a=10" in the a.txt file, change 10 to 0. If there is originally "a=0", then continue with the following batch processing.
If there is a line of text "b=我", delete this line of text (this line of text is not necessarily at the end of the text, may be in the middle, but definitely occupies a single line). If there is no "b=我", then add "b=你" to a.txt (I know the append command ">>", just want to know whether it can be inserted to a specific position, such as the Nth line)
Thank you all for your efforts.
If there is no solution under pure DOS, as long as there is a solution that can have the same effect under XP SP2 or 98, it is also okay. Thanks
P.S. I am a programming novice, and I have only made small things like boot disks with batch processing myself.

嗯，翻了翻旧帖。结果用change+if解决问题了。
谢谢
Well, I flipped through the old posts. As a result, I solved the problem by using change + if. Thanks

遇到过同样问题，你既然解决了，就把代码贴出来充实一下论坛啊！这个做法不厚道啊
Encountered the same problem. Since you solved it, post the code to enrich the forum! This is not decent.

我的问题是，有次下了四百多部htm格式的电子小说，不过不爽的是每一页中都含有相同的广告代码！我想用批处理来删除掉！如何做？
My question is that I once downloaded more than 400 e-novels in htm format, but the unpleasant thing is that each page contains the same advertisement code! I want to use batch processing to delete it! How to do it?

BAT也没有这么强啊。。他不是编程语言。
BAT is not that powerful either. It's not a programming language.

用sed更方便，sed很强
Using sed is more convenient, sed is very powerful

可以用DW，整站查找替换源码。我经常用

You can use DW, find and replace the source code for the entire site. I often use it

是的。我正需要这样的解决方法。

Yes. I am exactly in need of such a solution.

抄袭了些前辈的经验,看看行不行?:)
@echo off
call :replace my.txt aaa bbb >>my1.txt
goto :eof
:replace
setlocal ENABLEDELAYEDEXPANSION
for /f "tokens=1* delims=" %%i in (%1) do set var=%%i & echo !var:%2=%3!
endlocal
goto :eof
以上代码是把aaa替代成bbb的.应该可以,我试过了.
Copied some experiences from predecessors, let's see if it works? :)
@echo off
call :replace my.txt aaa bbb >>my1.txt
goto :eof
:replace
setlocal ENABLEDELAYEDEXPANSION
for /f "tokens=1* delims=" %%i in (%1) do set var=%%i & echo !var:%2=%3!
endlocal
goto :eof
The above code is to replace aaa with bbb. It should work, I have tried it.
