偶然看到的一个问答
Yay! I had given up hope of ever getting a pure batch solution. Nicely done.

get-cursor-position-via-windows-10-console-vt-100-escape-sequence
  1. @echo off
  2. for /F "delims=#" %%a in ('"prompt #$E# & for %%a in (1) do rem"') do set "ESC=%%a"
  3. call :get_cursor_pos
  4. exit /b
  5. :get_cursor_pos
  6. set "response="
  7. set pos=2
  8. :_get_loop
  9. REM *** Request Cursor position
  10. <nul set /p "=%ESC%[6n"
  11. FOR /L %%# in (1 1 %pos%) DO pause < CON > NUL
  12. for /F "tokens=1 skip=1 eol=" %%C in ('"REPLACE /W ? . < con"') DO (
  13.     set "char=%%C"
  14. )
  15. set "response=%response%%char%"
  16. set /a pos+=1
  17. if "%char%" NEQ "R" goto :_get_loop
  18. set response
  19. exit /b

牛逼,竟然还能用Escape屏幕控制码。但为什么 <nul set /p "=%ESC%[6n" 能将内容回填到StdIn?

更多玩法自己摸索:

微软对 终端 的支持从 WIN10 某版本开始, 仍在持续升级中

小提速,同可时也可以用来获取最大的行,列值。
  1. @echo off&setlocal enabledelayedexpansion
  2. ::文本只能保存为ansi编码,其它编码可能出错。
  3. ::Win 10 下测试通过。
  4. for /F "tokens=1 delims=#" %%a in ('"prompt #$E# & echo on & for %%b in (1) do rem"') do set "ESC=%%a"
  5. set/p=%ESC%[255;255H<nul
  6. for /l %%b in (2,1,7) do (
  7. if "!K!" neq "R" (
  8. set /p=%ESC%[6n<nul
  9. (for /l %%a in (1,1,%%b) do pause>nul
  10. for /f "tokens=2 delims=键" %%c in ('"xcopy /w . 2>nul"') do set K=%%c
  11. set str=!str!!k!
  12. )<con
  13. )
  14. )
  15. set /p in=当前窗口显示最大行;列:!str!,回车退出
