Win10: Move cursor position to 0,0

#1 Post by WiVi71 » 21 Mar 2020 16:28

I found that "FOR /F %A IN ('"TIMEOUT 1 > CON"') DO REM" command shows a different output than "TIMEOUT 1 > CON" command(In Windows 10).

The command moved the cursor position to 4,0
Also, several special characters were displayed on the screen.

So, this code moves cursor position to 0,0.

Code: Select all

:: I don't know if this code will work in other environment.
@ECHO OFF
FOR /F %%A IN ('"ECHO PROMPT $H | CMD"') DO SET "BS=%%A"
FOR /F %%A IN ('"TIMEOUT 1 > CON"') DO REM
<NUL SET /P "PRINT=%BS%%BS%%BS%%BS%TESTED IN WIN 10"
PAUSE > NUL

Also, according to this table, that output was:

Code: Select all

[BS]0[TAB][CR]/F %A IN ('"TIMEOUT 1 > CON"') DO REM
[TAB][CR]Waiting for 1 seconds, press a key to continue ...
But I'm not sure why ASCII TAB,CR was printed. :?:



EDIT: "CMD /C TIMEOUT 1 > CON" seems to work like "FOR /F %A IN ('"TIMEOUT 1 > CON"') DO REM". Tests on CMD.

Antonio did something like that before using Windows 8.1:

The codes we used before(timeout 1 > con) moved cursor position to 1,0
So you should have used a script to lift the cursor position up one line to move the cursor to 0,0

Code: Select all

@echo off
setlocal EnableDelayedExpansion

rem Get a BS and TAB control characters
for /F %%a in ('echo prompt $H ^| cmd') do set "BS=%%a"
for /F "skip=4 delims=pR tokens=2" %%a in ('reg query hkcu\environment /v temp' ) do set "TAB=%%a"
for /F "tokens=2 delims=0" %%a in ('shutdown /? ^| findstr /BC:E') do if not defined TAB set "TAB=%%a"

rem Leave some empty lines and do a PAUSE
echo Three empty lines below + pause
echo/
echo/
echo/
pause

rem Get width of screen buffer, set number of lines to go above
for /F "tokens=2" %%a in ('mode con ^| findstr "Col"') do set /A buffWid=%%a, linesAbove=3

rem Assemble the "go above" control string with the proper number of BSs
set "BSs="
set /A "cntBS = 2 + (buffWid + 7) / 8 * linesAbove"
for /L %%i in (1,1,%cntBS%) do set "BSs=!BSs!!BS!"

rem Move cursor up the desired number of lines
echo %TAB%!BSs!

echo Hello,
echo World
echo This line overwrites the one with PAUSE output

This code is available as shown in the following link.
viewtopic.php?p=54462#p54462

But this trick only works up to Windows 8.1..
Instead, "FOR /F %A IN ('"TIMEOUT 1 > CON"') DO REM" can move the cursor position to 0,0 without a string-up trick.

Hello WiVi71

What about move the cursor to position 0,0 using windows 10 escape sequences. I think is more easy and clear code:

Code: Select all

@ECHO OFF

ECHO LINE 1

FOR /F %%E IN (
'"PROMPT $E &FOR %%_ IN (_) DO REM CURSOR 0 BY @CARLOS"'
) DO <NUL SET /P "=%%E[1;1H"

ECHO LINE 2

PAUSE

In his first post in the topic (that i linked above) Antonio used:

Code: Select all

for /F %%a in ('timeout /T 1 ^> CON') do rem
(If i remember right:) Under win 8.1, that just behaved the same as without the for loop. So your above discovery was indeed new
and i didn't want to argue against that; i just wanted to point out, the same code behaved differently ("sth like that" but not "the same")
under win 8.1 (so if someone might be tempted to use that code for both systems, he/she/.../they might want to add a version check).


Sidenotes:
You might want to add the "/nobreak" switch.
Somehow i missed the "i'm not sure why ASCII TAB,CR was printed" part:
The characters are carriage return (CR, \r) and newline (NL, \n), so it's a normal (win) endline:

Code: Select all

>con cmd /cecho \r\n == 
Output:

Code: Select all

\r\n == ♪◙
