Search and replace text in a txt file by a batch file in Windows

问题

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++.

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

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

Regards and Thx.

回答1:

@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
)

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