Question

I like to have a batch file which checks if an entered text in a .txt file is the same.

Something like this:

@echo off
Set pass=
set /p pass=Enter your password:
......
......

The .txt file is pass.txt, and it should look something like this:

p2342ddd3

So what I want it to do, that an user have to type in the text from the pass.txt file (not looking at it obviously) and that the batch file checks if it is similar with the text from the pass.txt file.

Answer 1

This will require a combination of a for loop and simple if:

@echo off
:begin
set pass=
set /p pass=Enter your password: 
if {%pass%}=={} goto :begin
set authenticated=
for /f "tokens=*" %%a in (pass.txt) do (
    if {%%a}=={%pass%} set authenticated=true
)

if not defined authenticated (echo Invalid password & goto :begin)
exit /b 0
