WHY

举例：

@echo off
setlocal enabledelayedexpansion
(for /f "skip=1" %%i in ('findstr /n .* 1.txt') do (
    set "s=" & set /p s=
    echo;!s!
)) < 1.txt
pause

WHY

@echo off
for /f "delims=" %%i in ('findstr /n .* 1.txt') do (
    if defined s (
        setlocal enabledelayedexpansion
        echo;!s:*:=!
        endlocal
    )
    set "s=%%i"
)
pause

@echo off
PowerShell "$arr = type 1.txt; $arr[0..($arr.Count-2)]"
pause
