寫首選項

訊息可以用;

Write-Verbose "Detailed Message"
Write-Information "Information Message"
Write-Debug "Debug Message"
Write-Progress "Progress Message"
Write-Warning "Warning Message"

每個都有一個偏好變數;

$VerbosePreference = "SilentlyContinue"
$InformationPreference = "SilentlyContinue"
$DebugPreference = "SilentlyContinue"
$ProgressPreference = "Continue"
$WarningPreference = "Continue"

首選項變數控制如何處理訊息和後續執行指令碼;

$InformationPreference = "SilentlyContinue"
Write-Information "This message will not be shown and execution continues"

$InformationPreference = "Continue"
Write-Information "This message is shown and execution continues"

$InformationPreference = "Inquire"
Write-Information "This message is shown and execution will optionally continue"

$InformationPreference = "Stop"
Write-Information "This message is shown and execution terminates"

通過設定可以控制訊息的顏色為 Write-Error;

$host.PrivateData.ErrorBackgroundColor = "Black"
$host.PrivateData.ErrorForegroundColor = "Red"

類似的設定可用於 Write-Verbose，Write-Debug 和 Write-Warning。
