使用WMIC获取驱动器空间信息

问题描述

我试图让物理驱动器的信息与WMIC计算机得到的东西是这样的：

I'm trying to get info of the physical drives in a computer with wmic to get something like this:

Drive C:
500 GB Total
100 GB Free
20% Free

Drive D:
500 GB Total
100 GB Free
20% Free

我的code到目前为止是：

My code so far is:

for /f "usebackq tokens=*" %%a in (`wmic logicaldisk where "drivetype=3" get caption`) do (
echo "Drive=%%a"
for /f "usebackq delims== tokens=2" %%x in (`wmic logicaldisk where DeviceID='%%a'"
get FreeSpace /format:value`) do set FreeSpace=%%x
for /f "usebackq delims== tokens=2" %%x in (`wmic logicaldisk where "DeviceID='%%a'" get Size /format:value`) do set Size=%%x
echo FreeMB=%FreeSpace%
echo SizeMB=%Size%
set /a Percentage=100 * %FreeSpace% / %Size%
echo %%a is %Percentage% %% free
)

和我的输出是：

"Drive=Caption
No Instance(s) Available.
No Instance(s) Available.
FreeMB=9193357312
SizeMB=80024170496
Invalid number.  Numbers are limited to 32-bits of precision.
 is  % free
"Drive=C:
No Instance(s) Available.
No Instance(s) Available.
FreeMB=9193357312
SizeMB=80024170496
Invalid number.  Numbers are limited to 32-bits of precision.
is  % free
"Drive=E:
No Instance(s) Available.
No Instance(s) Available.
FreeMB=9193357312
SizeMB=80024170496
Invalid number.  Numbers are limited to 32-bits of precision.
 is  % free
"Drive=
No Instance(s) Available.
No Instance(s) Available.
FreeMB=9193357312
SizeMB=80024170496
Invalid number.  Numbers are limited to 32-bits of precision.
 is  % free

我得到了许多行甚至不具有一个驱动器，我无法格式化的价值，所以我可以计算百分比，或者在正常的格式显示值

I'm getting to many lines that don't even have a drive and I can't format the value so I can calculate the percentage, or show the values in a normal format

推荐答案

这可能会为你工作：code是在您的批处理文件的底部加入，并且使用

This may work for you: the code is to be added at the bottom of your batch file, and use

电话：HDD-信息

在code中显示的数据。

in your code to display the data.

goto :eof
:code by aGerman - display drive stats and bar graph (REMmed out)
:hdd-info
@echo off &setlocal
set "GB=1073741824"
for /f "skip=1 delims=" %%i in ('wmic logicaldisk get DeviceID^,FreeSpace^,Size') do (
  for /f "tokens=1-3" %%j in ("%%i") do call :output %%j %%k %%l
)
goto :eof
:output
if "%3"=="" (
  rem echo Unable to discover the drive properties.
  goto :eof
)
for /f "tokens=1-4" %%i in (
  'mshta vbscript:Execute("CreateObject(""Scripting.FileSystemObject"").GetStandardStream(1).Write(FormatNumber(%3/%GB%, 2) & "" "" & FormatNumber((%3-%2)/%GB%, 2) & "" "" & FormatNumber(%2/%GB%, 2) & "" "" & Round((%3-%2)*50/%3)):Close"^)'
) do (
  set "size=      %%i"
  set "used=      %%j"
  set "free=      %%k"
  set /a "nUsed=%%l, nFree=50-%%l"
)
echo(
echo       %1
echo Size: %size:~-10% GB
echo Used: %used:~-10% GB
echo Free: %free:~-10% GB
:: echo(
:: for /l %%i in (1 1 %nUsed%) do <nul set /p "=▒"
:: for /l %%i in (1 1 %nFree%) do <nul set /p "=█"
:: echo(&echo(&echo(
goto :eof
