Powershell - 某些结果的输出颜色 [英] Powershell - Output Color for certain results

问题描述

我正在运行下面的代码并且它有效.我想要做的是，在 Enabled 属性为 True 时的结果中，我希望文本 'True' 前景色为绿色，否则为红色.

I am running the code below and it works. What I am trying to do is, in the results when Enabled properties is True I would like to the text 'True' foreground color to be green otherwise if 'false' color Red.

与 Password never expires 属性相同，如果结果为 'True' 我希望文本 'True' 前景色为红色，否则如果它的 'False' 颜色为绿色.

The same with the Password never expires properties, if the result is 'True' I would like to the text 'True' foreground color to be Red otherwise if its 'False' color green.

我正在尝试将 if-else 语句放入代码中，但没有成功.

I am trying to fit an if-else statement into the code but have not been successfull.

代码:

Get-ADUser "user name"  -Properties Enabled,LockedOut,DisplayName,GivenName, SurName,Mail,LastLogon, Created,passwordlastset,Passwordneverexpires,msDS-UserPasswordExpiryTimeComputed, Description, office, Canonicalname | `
        Select-Object Enabled, 
        @{Expression={$_.LockedOut};Label='Locked';}, 
        @{Expression={$_.DisplayName};Label='Display Name';},
        @{Expression ={$_.GivenName};Label='Name';}, `
        @{Expression ={$_.SurName}; Label='Last Name'; }, 
        Mail, 
        @{Expression ={[DateTime]::FromFileTime($_.LastLogon)}; Label='Last Logon';}, 
        @{Expression={$_.Created};Label='Date Created';}, 
        @{Expression={$_.passwordlastset};Label='PW Last Reset';}, 
        @{Expression={$_.Passwordneverexpires};Label='PW Never Expires';},
        @{Name="PW Exp Date";Expression={[datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed")}}  ,
        Description, 
        Office,
        Canonicalname 
        Format-list

有什么建议吗?

推荐答案

这是一个可能的解决方案:

Here's a possible solution:

$Highlight = @{
    True = 'Red'
    False = 'Green'
}

$User = Get-ADUser "user name"  -Properties Enabled,LockedOut,DisplayName,GivenName,SurName,Mail,LastLogon,Created,passwordlastset,Passwordneverexpires,msDS-UserPasswordExpiryTimeComputed, Description, office, Canonicalname |
        Select-Object Enabled, 
        @{Expression={$_.LockedOut};Label='Locked';}, 
        @{Expression={$_.DisplayName};Label='Display Name';},
        @{Expression ={$_.GivenName};Label='Name';}, `
        @{Expression ={$_.SurName}; Label='Last Name'; }, 
        Mail, 
        @{Expression ={[DateTime]::FromFileTime($_.LastLogon)}; Label='Last Logon';}, 
        @{Expression={$_.Created};Label='Date Created';}, 
        @{Expression={$_.passwordlastset};Label='PW Last Reset';}, 
        @{Expression={$_.Passwordneverexpires};Label='PW Never Expires';},
        @{Name="PW Exp Date";Expression={[datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed")}},
        Description, 
        Office,
        Canonicalname | Format-list | Out-String

$User -split "`n" | ForEach-Object {
    $Output = $False
    If ($_ -match 'Enabled|PW Never Expires') {
        ForEach ($Entry in $Highlight.Keys){
            $Text = $_ -split $Entry
            If ($Text.count -gt 1) { 
                Write-Host $Text[0] -NoNewline
                Write-Host $Entry -ForegroundColor $Highlight.$Entry
                $Output = $true
                Break
            }
        }
    }

    If (-not $Output) { Write-Host $_ }
}

请注意，这应该特别适用于您使用 Format-List 获得的那种输出，但不是一个经过深思熟虑的突出显示功能，否则:例如，这将无法处理可能在同一行文本中多次出现.

Note that this should work for the sort of output you get with Format-List in particular but isn't a particularly well thought out highlighting function otherwise: e.g this won't handle words that might appear multiple times in the same line of text.

另外，仅供参考，以这种方式使用 PowerShell 通常不是最佳实践.您应该考虑编写输出到管道的 PowerShell 工具，而不是通过 Write-Host，这样您就可以在其他命令中操作结果，或将其转换(例如，转换为 CSV 等).

Also FYI working with PowerShell in this way isn't generally best practice. You should consider writing PowerShell tools that output to the pipeline and not via Write-Host, that way you can manipulate the results in other commands, or transform it (e.g to CSV etc.).
