我没有得到仅使用 W MIC 的批处理脚本中内存利用率的结果。我只获得总内存和可用内存（以字节为单位）。
那么如何获取以兆字节为单位的数据以及如何计算内存利用率百分比？
代码：-
@echo off
setlocal enabledelayedexpansion
set Times=0
for /f "skip=1" %%p in ('wmic cpu get loadpercentage') do (
set Cpusage!Times!=%%p
set /A Times+=1
)
echo CPU Percentage = %Cpusage0%%%
set Times=0
for /f "skip=1" %%p in ('wmic ComputerSystem get TotalPhysicalMemory') do (
set totalMem!Times!=%%p
set /A Times+=1
)
set Times=0
for /f "skip=1" %%p in ('wmic OS get FreePhysicalMemory') do (
set availableMem!Times!=%%p
set /A Times+=1
)
set Times=0
for /f "skip=1" %%p in ('wmic OS get FreePhysicalMemory ^|findstr physical') do (
set /a UsedMem= totalMem - availableMem
set usedMem!Times!=%%p
set /A Times+=1
)
set /a usedpercent=(usedMem*100)/totalMem
echo Free MEMORY = %availableMem0% Bytes
echo Total MEMORY = %totalMem0% Bytes

rem Total physical memory is in bytes which can be greater 2^31 (= 2 GB)
rem Windows command processor performs arithmetic operations always with
rem 32-bit signed integer. Therefore 2 GB or more installed physical
rem memory exceeds the bit width of a 32-bit signed integer and arithmetic
rem calculations are wrong on 2 GB or more installed memory. To avoid
rem the integer overflow, the last 6 characters are removed from bytes
rem value and the remaining characters are divided by 1073 to get the
rem number of GB. This workaround works only for physical RAM being
rem an exact multiple of 1 GB, i.e. for 1 GB, 2 GB, 4 GB, 8 GB, ...
rem 1 GB = 1.073.741.824 bytes = 2^30
rem 2 GB = 2.147.483.648 bytes = 2^31
rem 4 GB = 4.294.967.296 bytes = 2^32
rem 8 GB = 8.589.934.592 bytes = 2^33
rem 16 GB = 17.179.869.184 bytes = 2^34
rem 32 GB = 34.359.738.368 bytes = 2^35
rem But there is one more problem at least on Windows XP x86. About 50 MB
rem of RAM is subtracted as used by Windows itself. This can be seen in
rem system settings when 1.95 GB is displayed although 2 GB is installed.
rem Therefore add 50 MB before dividing by 1073.

我找到了一种使用下面脚本的方法，希望它能有所帮助。这也会计算百分比
for /f "tokens=2 delims==" %%a in ('wmic computersystem get
TotalPhysicalMemory /value') do (
for /f "delims=" %%b in ("%%a") do (
Set "MEM=%%b"
)
)
for /f "tokens=2 delims==" %%a in ('wmic OS get FreePhysicalMemory
/value') do (
for /f "delims=" %%b in ("%%a") do (
Set "AVMEM=%%b"
)
)
Set /a TotalPhysicalMemory = %MEM:~0,-3%/1024/1024
Set /a AvailablePhysicalMemory = %AVMEM%/1024/1024
echo TotalPhysicalMemory: %TotalPhysicalMemory% GB
echo AvailablePhysicalMemory: %AvailablePhysicalMemory% GB
set /a UsedPhysicalMemory=TotalPhysicalMemory - AvailablePhysicalMemory
set /a UsedPercent=(UsedPhysicalMemory * 100)/TotalPhysicalMemory
echo Memory usage: %UsedPercent%%%
输出看起来像这样
::TotalPhysicalMemory: 262 GB
::AvailablePhysicalMemory: 240 GB
