在Windows中用批处理文件搜索并替换txt文件中的文本 [英] Search and replace text in a txt file by a batch file in Windows

问题描述

我有一个大约100 mb至500 mb的大文件，打开它需要更多时间，而且由于记事本或notepad ++的响应缓慢，我也无法更改它.

I have a huge file approx 100 mb to 500 mb, it take more time to open it and I cannot change it also due to slow response in Notepad or notepad++.

我只需要替换REF号，而这仅是文件中的一次.

I have requirement to replace only REF Number and this is only one time in the file.

我可以在命令提示符下有一个批处理文件/脚本，以便替换文本吗?

Can I have a Batch file/ Script in Command prompt so that I can replace the text?

问候和感激之情.

推荐答案

@echo off
set "toreplace=REF"
for /f "tokens=* delims= " %%a in (yourfile.txt) do (
set "line=%%a"
setlocal enabledelayedexpansion
set "line=!line:%toreplace%=!"
echo !line! >>newfile.txt
)

此代码从yourfile.txt删除所有REF字符串，并将其输出到newfile.txt.
不是我的代码.

this code deletes all REF strings from yourfile.txt and outputs it to newfile.txt.
not my code.
