在powershell中更改输出颜色

Question

尝试查看是否可以使用以下几行更改输出的颜色。请注意，这不是完整的代码，只是其中的一部分：

$ADInfo `
    | Format-List `
        @{ Name = "Full Name"; Expression = { $_.name } },
        @{ Name = "Display Name"; Expression = { $_.displayname } },
        @{ Name = "User ID"; Expression = { $_.samaccountname } },
        @{ Name = "Email"; Expression = { $_.mail } },
        @{ Name = "Exchange Version"; Expression = { $_.msExchVersion } },

如果可能的话，我想单独更改名称和输出的颜色。

输出：

Function Write-HostColoured{
    [cmdletbinding()]
    Param(
        [parameter(Mandatory=$true,ValueFromPipeline=$true)]
        $Input,
        [parameter(Mandatory=$true)]
        [string]$ColouredProperty,
        [System.ConsoleColor]$Colour = "Red"

    )

    # Get all the note properties of the object which we need for output and determining conditional formatting.
    $properties = $input | gm -MemberType NoteProperty | Select-Object -ExpandProperty name

    # Find the property with the longest length. Used for aligning output. 
    $longestProperty = $properties | ForEach-Object{$_.Length} | Measure-Object -Maximum | Select-Object -ExpandProperty Maximum

    # Check if the property to colour requested is in $properties
    If($properties -notcontains $ColouredProperty){Write-Warning "Input object does not contain the property $ColouredProperty"}

    # Insert Line break between objects. 
    Write-Host

    ForEach($singleObject in $Input){
        $properties | ForEach-Object{
            Write-Host ("{0,-$longestProperty} : " -f $_) -NoNewline

            # Check if the property requires a colour formatting
            If($_ -eq $ColouredProperty){
                Write-Host $singleObject.$_ -ForegroundColor $Colour
            } Else {
                Write-Host $singleObject.$_
            }
        }

        # Insert Line break between objects. 
        Write-Host
    }
}

Import-Csv C:\temp\data.csv -header "Col123fff1","cl2","col3","col4" | Write-HostColoured -ColouredProperty Col3

样本输出

说明

认为这需要根据您的评论进行改进，但让我们从这个开始。它将从一个对象（使用Import-CSV 测试）获取管道输入，然后模拟Format-List 的输出。在使用Write-Host 输出时，如果正在处理的属性与$ColouredProperty 匹配，则应用$colour 定义的前景色。

这目前仅在您需要为一列着色时才有效，但我可以看到这也为条件格式设置了哈希表输入。

如果我们走在正确的轨道上，请告诉我。

条件着色

如果您更改 if 语句并添加另一个子句，您可以轻松地根据条件使着色成为条件

If($_ -eq $ColouredProperty -and $singleObject.$_ -match "\d")

它使函数的可转移性降低，但它会起作用。我用它来突出显示所有带有数字的文件名。

Get-ChildItem C:\temp -filter *.txt | Select Name,Length,Directory | Write-HostColoured -ColouredProperty Name
