关于获取windows系统参数方法

  前一阵写了一个获取网络内主机类型的脚本，没有写任何解释类的说明直接发上来造成好多兄弟们有很多疑问。今天就拣几个有特点的功能说明一下。

   获取windows系统或者性能参数。

   在powershell出现之前系统管理员习惯用VB来实现获取以上参数的功能（当然现在也可以），但本次文章的重点主是说powershell怎么实现获取以上参数信息，Powershell提供了很多扩展的功能可以直接访问.net框架，WMI，COM自动化和API的调用等。

   下面我们举例说明一哈通过WMI获取主机的内存信息：

   1获取本地主机空余内存大小：

1

2

<code>[PS]</code> <code>C:\&gt;(GWMI win32_OperatingSystem).FreePhysicalMemory</code>

<code>1245384</code>

   2获取本地主机的总内存大小：

<code>[PS]</code> <code>C:\&gt;(GWMI win32_OperatingSystem).TotalVisibleMemorySize</code>

<code>4166596</code>

   3如果我们想查看还能查看还有哪些类可以获取，按如下操作就可以看到：

<code>ConvertToDateTime                         ScriptMethod System.Object ConvertToDateTime();</code>

  4 如果我们想获取远程主机的参数应该怎么操作呢只需加上-computer参数比如：

<code>[PS]</code> <code>C:\&gt;(GWMI</code> <code>-computer</code> <code>bjexfe01  win32_OperatingSystem).TotalVisibleMemorySize</code>

<code>33543988</code>
