Question

I have a batch script made in notepad. It works, but there’s 2 segments of the script that make it close the cmd, and I just can’t understand why.

Here’s the script

@echo off
setlocal enabledelayedexpansion
title JC-ServerManager v1.0.0

set "database=admins.txt"
set "try_file=tryvalue.txt"

:: Leitura do valor de 'try' a partir do ficheiro 'tryvalue.txt'
if exist "%try_file%" (
    set /p try=<"%try_file%"
) else (
    set /a try=3
    echo 3 >"%try_file%"
)

:START
cls
powershell -Command Write-Host -NoNewLine -ForegroundColor Yellow " ----------------------------- Server Manager v1.0.0 ----------------------------- " & echo.

:: Verifica se o utilizador está bloqueado
if "%try%" equ "blocked" (
    powershell -Command Write-Host -NoNewLine -ForegroundColor Red "Your account is blocked. Please contact server admin to recover your permission." & echo.
    echo Contact:
    echo ...Email: [email protected]
    echo ...Phone: +351 967 041 910
    echo. & pause
    exit /b
)

echo. & echo LOGIN: & echo.

set /p "user=...User: "
set /p "password=...Password: "

echo. & echo Checking data...

set "authenticated=false"
set "user_found=false"
set "user_status=OK"
set "user_permission=DEFAULT"

:: Verifica se o nome de usuário e a senha não estão vazios
if "%user%"=="" (
    powershell -Command Write-Host -NoNewLine -ForegroundColor Red "User cannot be empty" & echo.
    echo. & pause
    goto :START
)

    powershell -Command Write-Host -NoNewLine -ForegroundColor Red "Password cannot be empty" & echo.
    echo. & pause
    goto :START
)

        if "%password%" equ "%%c" (
            if "%%d" equ "BLOCKED" (
                powershell -Command Write-Host -NoNewLine -ForegroundColor Red "Your account is blocked. Please contact server admin to recover your permission." & echo.
                echo Contact:

                echo. & pause
                exit /b
            ) else (
                set "authenticated=true"
                set "user_permission=%%e"
                goto :AUTHENTICATED
            )
        )
    )
)

:: Verifica se o usuário foi encontrado mas a senha estava incorreta
if "!user_found!"=="true" (
    powershell -Command Write-Host -NoNewLine -ForegroundColor Red "Incorrect password" & echo.
    set /a try-=1
    if !try! equ 0 (
        :: Atualiza o status do usuário para BLOCKED
        (for /f "tokens=1,2,3,4,5 delims=:" %%a in ('type "%database%"') do (

        )) > "%database%"

    )
    echo. & pause
    goto :START
)

if "!authenticated!"=="false" (
    powershell -Command Write-Host -NoNewLine -ForegroundColor Red "User not found or incorrect password" & echo.
    echo. & pause
    goto :START
)

:AUTHENTICATED
powershell -Command Write-Host -NoNewLine -ForegroundColor Green "You have been successfully authenticated!" & echo. & pause

set /a try=3

echo. & echo OPTIONS:

    exit /b
) else goto :AWSERROR

echo profile

cls
echo stats

goto :OPTIONS

:CONNECT
cls

cls

pause
goto :OPTIONS

:AWSERROR
powershell -Command Write-Host -NoNewLine -ForegroundColor Red "Error: Invalid option. Please choose one from the option menu." & echo. & pause
cls
goto :OPTIONS

endlocal
exit /b

The 2 segments causing problems to the script are:

:: Verifica se o usuário foi encontrado mas a senha estava incorreta
if "!user_found!"=="true" (
    powershell -Command Write-Host -NoNewLine -ForegroundColor Red "Incorrect password" & echo.
    set /a try-=1
    if !try! equ 0 (
        :: Atualiza o status do usuário para BLOCKED
        (for /f "tokens=1,2,3,4,5 delims=:" %%a in ('type "%database%"') do (
            if "%%b" equ "%user%" (
                echo %%a:%%b:%%c:BLOCKED:%%e
            ) else (
                echo %%a:%%b:%%c:%%d:%%e
            )
        )) > "%database%"
        echo blocked >"%try_file%"
    ) else (
        echo !try! >"%try_file%"
    )
    echo. & pause
    goto :START
)

and

:: Verifica se as credenciais estavam incorretas e o usuário não foi encontrado
if "!authenticated!"=="false" (
    powershell -Command Write-Host -NoNewLine -ForegroundColor Red "User not found or incorrect password" & echo.
    echo. & pause
    goto :START
)

They should show an error message, just like every other option, but instead, if the user or password are wrong, the cmd just closes. If they’re empty or correct it works, even the blocked status accounts works. The only issue is with the incorrect credentials.

Btw I am using 2 .txt files to run the script:

tryvalue.txt

and admins.txt

1:user1:password1:OK:ADMIN
2:user2:password2:OK:DEFAULT
3:user3:password3:BLOCKED:DEFAULT

I’ve tried to use an older version of the script and it works, but not with all the options I want it to be able to do.
