Creating a simple finger application with batch

I would like to make a simpl开发者_如何学JAVAe batch application that does two things.

1. Asks the user to input a name, example "vega"
2. Runs "finger vega@mail.example.com" and displays the output of that command.

The following does the first thing, but I am not able to output the result from the finger.

 @ECHO OFF

 :begin

 echo Enter the name of the user you are looking for:
 set INPUT=
 set /P INPUT=Name: %=%
 finger -l %INPUT%@mail.example.com

 pause
 GOTO begin

---

Something like this maybe.

@echo off
setlocal
set INTERVAL=10


echo Enter the name of the user you are looking for:
set /P INPUT=
echo INPUT=%INPUT%
echo Name: %INPUT%

:LOOP
    for /F "usebackq tokens=*" %%a IN (`finger -l %INPUT%@mail.example.com`) DO set OUTPUT=%%a
    echo OUTPUT=%OUTPUT%
    if "%OUTPUT%"=="something" (goto LOOPEND)
    call :SLEEP %INTERVAL%
goto LOOP
:LOOPEND

goto :eof

:: -------------- Sleep function -------------------
:SLEEP
    set /a SECS=%1
    set /a SECS+=1
    ping 127.0.0.1 -n %SECS% -w 1000 > nul
goto :eof
