无法在cmd中通过管道传递cmdlet对象 [英] Unable to pipe cmdlet objects in cmd

问题描述

我正在使用此powershell命令来获取特定的用户个人资料

i am using this powershell command to fetch a particular user profile

"Get-WmiObject -Win32_UserProfile类| Where-Object {$ _.LocalPath -eq'C:\ Users \ Pela'}""

"Get-WmiObject -Class Win32_UserProfile | Where-Object {$_.LocalPath -eq 'C:\Users\Pela'}"

但是当我通过调用powershell在cmd中使用相同的命令时无法将对象识别为内部或外部命令，可操作程序或批处理文件"

But when i am using this same command in cmd by invoking powershell i am getting 'Where-Object is not recognized as an internal or external command,operable program or batch file'

我在cmd中运行的命令如下:-"powershell Get-WmiObject -Class Win32_UserProfile | Where-Object {$ _.LocalPath -eq'C:\ Users \ Pela'}""

The command i am running in cmd is as follows :- "powershell Get-WmiObject -Class Win32_UserProfile | Where-Object {$_.LocalPath -eq 'C:\Users\Pela'}"

我只需要从cmd运行此命令，我没有其他选择.所以请给我一个"Where-Object"的替代方法

I need to run this command from cmd only , i don't have any other options . So please give me an alternative to "Where-Object"

推荐答案

所以，请给我一个"Where-Object"的替代方法

powershell Get-WmiObject -Class Win32_UserProfile | Where-Object {$_.LocalPath -eq 'C:\Users\Pela

您不需要其他选择.上面的命令失败，因为管道 | 是由 cmd 外壳而不是 PowerShell 解释的.

You don't need an alternative. The above command is failing because the pipe | is being interpreted by the cmd shell and not by PowerShell.

如果您转义管道 ^ | ，则管道由PowerShell命令按预期完成:

If you escape the pipe ^| then the piping is done by the PowerShell command as expected:

powershell Get-WmiObject -Class Win32_UserProfile ^| Where-Object {$_.LocalPath -eq 'C:\Users\Pela

示例:

F:\test>powershell Get-WmiObject -Class Win32_UserProfile ^| Where-Object {$_.LocalPath -eq 'C:\Users\DavidPostill'}
