Question

我想过滤我的输出。如果我得到以下脚本的结果。我怎样才能得到specifix过程？ -这是我的建议，但确实有效：

Function Get-CPUProcess
{ 
$properties=@(
    @{Name="Name"; Expression = {$_.name}},
    @{Name="PID"; Expression = {$_.IDProcess}},
    @{Name="CPU (%)"; Expression = {$_.PercentProcessorTime}},
    @{Name="Memory (MB)"; Expression = {[Math]::Round(($_.workingSetPrivate / 1mb),2)}}
    @{Name="Disk (MB)"; Expression = {[Math]::Round(($_.IODataOperationsPersec / 1mb),2)}}
    @{Name="Path";Expression = {(Get-Process -Id $_.IDProcess).Path}}
)
$ProcessCPU = Get-WmiObject -class Win32_PerfFormattedData_PerfProc_Process |
    Select-Object $properties |
    Sort-Object "CPU (%)" -desc |
    Select-Object -First 5 |
    Format-Table -AutoSize
    $ProcessCPU
}
Get-CPUProcess -Filter {processname -like "firefox*"} | select * | Out-File C:\filename.txt

天真的方法看起来像：

$properties=@(
    @{Name="Name"; Expression = {$_.name}},
    @{Name="PID"; Expression = {$_.IDProcess}},
    @{Name="CPU (%)"; Expression = {$_.PercentProcessorTime}},
    @{Name="Memory (MB)"; Expression = {[Math]::Round(($_.workingSetPrivate / 1mb),2)}}
    @{Name="Disk (MB)"; Expression = {[Math]::Round(($_.IODataOperationsPersec / 1mb),2)}}
    @{Name="Path";Expression = {(Get-Process -Id $_.IDProcess).Path}}
)
$ProcessCPU = Get-WmiObject -class Win32_PerfFormattedData_PerfProc_Process |
    Select-Object $properties |
    Sort-Object "CPU (%)" -desc |
    Select-Object -First 5 |
    Format-Table -AutoSize
    $ProcessCPU

如果性能至关重要，请在选择前5个项目后加入Get-Process：

$properties=@(
    @{Name="Name"; Expression = {$_.name}},
    @{Name="PID"; Expression = {$_.IDProcess}},
    @{Name="CPU (%)"; Expression = {$_.PercentProcessorTime}},
    @{Name="Memory (MB)"; Expression = {[Math]::Round(($_.workingSetPrivate / 1mb),2)}}
    @{Name="Disk (MB)"; Expression = {[Math]::Round(($_.IODataOperationsPersec / 1mb),2)}}
)
$ProcessCPU = Get-WmiObject -class Win32_PerfFormattedData_PerfProc_Process |
    Select-Object $properties |
    Sort-Object "CPU (%)" -desc |
    Select-Object -First 5
$ProcessCPU | select *,@{Name="Path";Expression = {(Get-Process -Id $_.PID).Path}} | Format-Table
