进度条 Dos

Question

我是dos批处理命令的新手，我想实现图中那样的进度条。首先，你必须初始化进程值，并计算它的百分比，你必须使用进度条来显示它。

你可以按Alt+219和Alt+176键来实现进度条。

这是我目前所做的。

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%
)

Answer 1

历史。

ANSI序列是作为ANSI序列的一部分加入的。红石更新 (而且是删了又加，提了又删。此处)，所以才有 只适用于Windows 10

删除了 FORFILES现在，速度快250倍

功能化版本 @史蒂芬的回答

脚本现在被中止了马上当按下Ctrl-C时

根据@Joseph的要求进行编辑。

使用以下组合 ANSI序列和的能力 FORFILES 打印ASCII字符

编辑: 本回答以1条秒为限，但 兼容从7开始跨越所有版本的windows。 (在一些 /NOBREAK 开关不支持）。)

在 DosTips，@Aacini发现 TIMEOUT 转至 CON 把光标带回家！@jeb 还表明，可以通过管道消除输出 | (通常 TIMEOUT 不支持管道，所以 SET /P 被使用）。) 然而，要删除顶部的倒计时是（几乎）不可能的。

Answer 2

这在这里可以工作（非常快！）。

编辑: 修改了 "可变步数条 "的代码

@echo off
SetLocal EnableDelayedExpansion

rem Define the "amounts" of each one of the (7) steps that comprise this job
set "amounts= 10 6 2 9 3 7 4"
set width=60

set "off="
set "on="
for /F "tokens=1,2" %%X in ('FORFILES /M "%~nx0" /C "cmd /c echo 0xDB 0xB0"') do (
   for /L %%i in (1,1,%width%) do set "on=!on!%%X" & set "off=!off!%%Y"
)

rem Get CR, BS and TAB ASCII control characters:
for /F %%a in ('copy /Z "%~f0" nul') do set "CR=%%a"
for /F %%a in ('echo prompt $H ^| cmd') do set "BS=%%a"
set "TAB="
rem First, try the method for Windows XP
for /F "skip=4 delims=pR tokens=2" %%a in ('reg query hkcu\environment /v temp' ) do set "TAB=%%a"
rem Then, the method for newer versions
rem http://www.dostips.com/forum/viewtopic.php?f=3&t=1733&p=6840#p6853
for /F "tokens=2 delims=0" %%a in ('shutdown /? ^| findstr /BC:E') do if not defined TAB set "TAB=%%a"
rem String to go up one line in SET /P command
set "LineUp=%TAB%!BS!!BS!!CR!"

cls
echo Percentage of values processed
echo/
echo %TAB%%off%
echo %TAB%Percent: 0%%
echo %TAB%Processing: 0/%processValue%

set /A "processValue=0, summa=0"
for %%a in (%amounts%) do set /A processValue+=%%a
for %%N in (%amounts%) do (
   set /A "summa+=%%N, Percent=summa*100/processValue, PercentOn=Percent*width/100
   for %%i in (1,1,4) do set /P "=.!LineUp!" < nul
   for %%p in (!PercentOn!) do echo %TAB%!on:~0,%%p!
   echo %TAB%Percent: !Percent!%%
   echo %TAB%Processing: !summa!/%processValue% (current: %%N^)  

   timeout /T %%N > nul

)

关于 "上升一行 "的方法，详见将光标移至 任何职位 只用ECHO命令

注: 将光标向上移动一行的方法在所有的Windows版本中都适用。除了Windows 10使用新的控制台. 你需要在cmd.exe窗口控制台启用 "Legacy模式 "才能使这个方法正常工作......

Answer 3

对HackingAddict1337的代码做了一些小的修改，就可以有一个固定的（可选择的）总长度的条形图。

@echo off
cls
SETLOCAL EnableDelayedExpansion

set /a "processValue=200"
set "bar=0xDB" Character used by progress bar (SUPPORTS HEX)
set "tbd=0xB0"
set "barLength=40"
( set LF=^
%=-----------DO NOT REMOVE THIS LINE. the LF variable is for future use in a function, it's currently useless-----------=%
)
FOR /F %%B in ('FORFILES /P "%~dp0." /M "%~nx0" /C "cmd /c echo(!bar!"') do set "bar=%%B"
FOR /F %%B in ('FORFILES /P "%~dp0." /M "%~nx0" /C "cmd /c echo(!tbd!"') do set "tbd=%%B"
FOR /F %%B in ('copy /Z "%~f0" nul') do set "CR=%%B"
FOR /F %%B in ('prompt $E ^& ^<nul cmd /k') do set "ESC=%%B"
for /l %%N in (0,1,%barLength%) do set "emptybar=!emptybar! "

echo Starting at %time%!LF!
for /l %%N in (0 1 !barLength!) do echo(!LF!%ESC%[2A%ESC%[%%NC%tbd%
for /L %%N in (0 1 %processValue%) do (
  set /a showBar=%%N*barLength/processValue
  set /a percentage=%%N*100/processValue
  echo(Processing: %%N / %processValue% = !percentage!%%!LF!%ESC%[2A%ESC%[!showBar!C%bar%
  ping -4 -n 1 127.0.0.1 >nul 
)
echo !LF!Finished at %time%
pause>nul
ENDLOCAL

(根据HackingAddicts的快速代码改编)

约瑟夫的担忧。

你缺少 "测量条 "的样子，这个应该是ALT+176的样子，这是我认为的代码 "echo [%emptybar%]"。改编成你想要的样子。
你缺少的另一个东西是非常简单的百分比，例如：百分比： 10%。也是改编的。

Starting at 15:58:44,10
 ██████░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░
Processing: 32 / 200 = 16%

进度条的速度是可变的这意味着每一步的速度不是恒定的。那是因为四舍五入的原因。我们对此无能为力，除了我们让 processValue 与...相当 barLength 或整数倍。

Answer 4

如果你想，你可以轻松打印ascii码与此应用程序。

下载网址。

https:/mega.nzfile2AZA3Y5T#y8z1aIKJHPiHmnlkgv-dYmn0J2fozz83uGdXS7umyLE

进度条也有很多字符。

语法很简单。

char [ascii code] [ascii code]

例如，你可以添加空字符

char 186 186 201 186

你也可以添加空字符。

char 186 " " 186
