如何从Windows命令行检索可用的RAM？

Question

Windows或第三方程序中是否有可以检索计算机上可用RAM的命令行实用程序？(因为我不相信这可以在纯JAVA中完成,因为它在虚拟机中运行,具有预设/分配的RAM)？

Answer 1

systeminfo 是一个输出系统信息的命令,包括可用内存

Answer 2

wmic OS get FreePhysicalMemory /Value

Answer 3

使用wmic computersystem get TotalPhysicalMemory.例如:

C:\>wmic computersystem get TotalPhysicalMemory
TotalPhysicalMemory
4294500352

Answer 4

SysSnternals提供了大量有用的低级工具.

并且psinfo可能是最有用的.

我使用了以下psinfo开关:

-h        Show installed hotfixes.
-d        Show disk volume information.

示例输出是这样的:

c:> psinfo \\development -h -d

Answer 5

wmic OS get TotalVisibleMemorySize /Value

注意不要TotalPhysicalMemory像其他地方一样

Answer 6

有点旧,但我想知道类似的.刚刚添加我自IMO以来遇到的解决方案,最好的答案来自Everardo w/Physical Memory

wmic OS get FreePhysicalMemory /Value

这让我更深入地了解wmic ...请记住,Free Physical Memory不是要看的类型.

wmic OS get FreePhysicalMemory,FreeVirtualMemory,FreeSpaceInPagingFiles /VALUE

这会返回类似......

FreePhysicalMemory=2083440
FreeSpaceInPagingFiles=3636128
FreeVirtualMemory=842124
