Set file=

Set / p file= Please pull the file you want to process to this window:

Set "file=%file:" =% "

Echo.

Set all=

Set / p all= Please enter a replacement string:

Cd. > "% file%_tmp.txt"

Setlocal enabledelayedexpansion

For / f "tokens=1* delims=:"% I in ('findstr / n. * "% file%"') do (
