How to pull email address and password from text file with CMD?

Solution 1:

Try this loop with find conditioned by delimiters and tokens...

@echo off && setlocal enabledelayedexpansion

set "_log=.\mail.txt" && cmd /v /c cd.>!_log!

for /f "tokens=* delims=" %%i in ('type .\file.txt')do echo/%%~i|find "@" >nul && (
   for /f "tokens=1-3 delims=:" %%I in ('echo/%%~i')do echo/%%~I|find "@" >nul && (
    set "_m_p=%%~I:%%~J")||set "_m_p=%%~J:%%~K")&& for %%E in ("%%~J")do >>!_log! (
      echo/!_m_p: =!|find "@")

Solution 2:

There is not much new here. This is how I would have written It Wasn't Me's answer.

@REM Win10 64-bit Pull email address:password from text file using CMD: 
@REM Combo: [email protected]:password
@REM some text here 
@REM As Combo: [email protected]:password@1
@REM [email protected]:youtube123
@echo off 
cd.> mail.txt
for /f "tokens=* delims=" %%i in ('type file.txt') do echo %%~i | find "@" >nul && (
for /f "tokens=1-3 delims=:" %%I in ('echo %%~i') do echo %%~I | find "@" >nul && (
set "_m_p=%%I:%%J") || set "_m_p=%%J:%%K") && (
setlocal enableDelayedExpansion
for %%E in ("%%J") do echo !_m_p: =! | find "@">> mail.txt 
)
exit /b

Or:

@echo off & cd.> mail.txt & for /f "tokens=*delims=" %%i in ('type file.txt')do (
echo %%~i|find "@">nul && for /f "tokens=1-3delims=:" %%I in ('echo %%~i')do (
echo %%~I|find "@">nul && set "_m_p=%%I:%%J" || set "_m_p=%%~J:%%~K") && for /f %%E in ('
echo %%~J')do cmd /v/c echo !_m_p: =!|find "@")>> mail.txt
