如何使用call命令批量验证密码

Question

So I have this code

@echo off  
set /p pass=Input Pass:  
call rig.txt   
if %pass%==rig.txt goto right  
goto wrong  
:wrong  
echo Authentication Failed!  
pause  
exit  
:right  
echo correct  
pause  

So instead of having something like this

@echo off  
set /p pass=Input Pass:  
if %pass%==randompassword goto right  
goto wrong  
:wrong  
echo Authentication Failed!  
pause  
exit  
:right  
echo correct  
pause 

Im trying to get it so it calls rig.txt which has my password in it and checks if i inputed the right password. Please help!

Answer 1

@echo off  

rem Read right password saved in rig.txt file
set /P rightPass=< rig.txt

set /p pass=Input Pass:  
if %pass% == %rightPass% goto right  
echo Authentication Failed!  
pause  
exit  

:right  
echo correct  
pause
