管道是由管道操作员 (|) (ASCII 124) 连接的一系列命令。 每个管道操作员将上一个命令的结果发送到下一个命令。 可以将第一个命令的输出作为第二个命令的输入进行处理。 该输出可以发送到另一个命令。 结果是由一系列简单命令组成的复杂命令链或管道。
您可以藉由在命令提示字元出現 (ASCII 62) 重複的大於字元來偵測巢狀提示。 如需自定義提示的詳細資訊,請參閱about_Prompts。 您可以使用自動變數來尋找巢狀層級$NestedPromptLevel。 自動變數$PSDebugContext會在本機範圍中定義。 您可以使用變數的存在$PSDebugContext來判斷您是否在調試程式內執行。 例如: Power...
