Batch script to find and replace a string in text file within a minute for files up to 12 MB

Question

I have written a batch script to replace a string in text file.

Following is the script.

@echo off &setlocal
set \"search=%1\"
set \"replace=%2\"         


        

Answer 1

How about this, folks?

set search=%1
set replace=%2
set textfile=Input.txt    

set line1=with open('%textfile%', 'rw') as f:
set line2=f.write(f.read().replace('%search%', '%replace%'))
python -c "%line1%%line2%"

Muhahaha

Edit:

In a crazy oneliner

python -c "with open('%textfile%', 'rw') as f: f.write(f.read().replace('%search%', '%replace%'))"
