如何將文件內容分配給變量？

Question

@echo off 
SET str1=type %1 
SET str2=type %2 
echo File1: %str1% 
echo 
echo File2: %str2% 

你可能知道我想要什麼，但是命令行解釋器沒有。如何正確地做到這一點？

PS。我的意思是整個內容，不僅是第一行！

對於內容（全系）：

@echo off &setlocal enabledelayedexpansion 
set "files=1" 
if "%~1"=="" set "files=" 
if "%~2"=="" set "files=" 
if not defined files echo Missing filename(s^).&goto:eof 
:: read the first file 
set /a cnt1=0 
for /f "usebackqdelims=" %%i in ("%~1") do set /a cnt1+=1 &set "str1!cnt1!=%%i" 
:: read the second file 
set /a cnt2=0 
for /f "usebackqdelims=" %%i in ("%~2") do set /a cnt2+=1 &set "str2!cnt2!=%%i" 
:: write the first file 
echo File1: 
for /l %%i in (1,1,%cnt1%) do echo !str1%%i! 
:: write the second file 
echo File2: 
for /l %%i in (1,1,%cnt2%) do echo !str2%%i! 
endlocal
