Progress Bar Dos

I'm new to dos batch commands and I want to achieve the progress bar like in the picture. First you have to initialize the process value and the calculate the percentage of it and you have to display it using the progress bar.

You can do Alt+219 and Alt+176 for progress bar

Here's what i have done so far. 

echo off
cls
SetLocal EnableDelayedExpansion
set processValueString=200
set a/ processValue=200
set a/ percentage=0

echo Process value: %processValueString%

for /l %%a in (1,1, %processValue%) do (
    set a/ percentage = %%a / %processValue% * 100
    echo Percent: !percentage! %
    echo Processing: !a! / %processValue%
)
Solution

  • ANSI sequences were added as a part of the Redstone Update, so it will only work from Windows 10+

    Use a combination of ANSI sequences and the ability of FORFILES to print ASCII characters

    Edit: This answer is limited to 1 bar/second, but is compatible across all versions of windows from 7. (On some the /NOBREAK switch is unsupported.)

    At DosTips, @Aacini discovered TIMEOUT redirected to CON brings the cursor home! @jeb also showed that the output can be eliminated via piping | (normally TIMEOUT does not support piping, so SET /P is used.) However, it is (nearly) impossible to remove the countdown at the top.
