如何将文件内容分配给变量？

Question

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

您可能知道我想要什么，但命令行解释器却没有。怎么做得好？

PS。我的意思是整个内容，不仅仅是第一行！

Answer 1

对于内容（所有行）：

@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
