问题:

In a batch file, I want to write a "counter" to the screen without scrolling stuff off the screen. I have

FOR /L %%i IN (1,1,1000) DO (
< NUL set /P="Count= %%i"
)

{There is no space between < LT> NUL but this stops the line from showing in the question.}

This command doesn't add a LF or CR, but I do want a CR, just no LF.

The end result should be

Count= X

where X is "counting" from 1 to 1,000.

回答1:

@echo off
setlocal EnableDelayedExpansion

rem Get a Carriage Return (Ascii 13) in CR variable:
for /F %%a in ('copy /Z "%~F0" NUL') do set "CR=%%a"

FOR /L %%i IN (1,1,1000) DO ( < NUL set /P "=Count= %%i!CR!" )

回答2:

@echo off
setlocal EnableDelayedExpansion
set cnt=0
for /F %%a in ('copy /Z "%~F0" NUL') do set "CR=%%a"


FOR /L %%a IN (1,1,5) DO ( 
 call :cnt
 timeout /t 1 >nul
 < NUL set /P "=!er!!CR!"
 )
echo.
pause
exit 
:cnt
set /a cnt=!cnt!+1
if %cnt% == 1 set er=Hello!                             
if %cnt% == 2 set er=I am Soubhik Biswas                                 
if %cnt% == 3 set er=My Roll Is 40                          
if %cnt% == 4 set er=Is Study In Class VIII-C       
goto :eof
