Cmdlet Output Object List in Windows PowerShell
What is the output object list of a cmdlet in Windows PowerShell?
✍: FYIcenter.com
Many cmdlets do return a list of objects, not just a single object.
If there is no more cmdlet in the cmdlet pipeline, the output object list will converted to a text table with properties of each object displayed as fields in a row.
For example, cmdlet "get-service" will return a list of ServiceController objects.
PS C:\fyicenter> get-service sql* Status Name DisplayName ------ ---- ----------- Stopped SQLAgent$SQLEXP... SQL Server Agent (SQLEXPRESS) Stopped SQLBrowser SQL Server Browser Stopped SQLWriter SQL Server VSS Writer
If there is a next cmdlet in the cmdlet pipeline, the entire list of objects will be passed to the next cmdlet for further processing:
PS C:\fyicenter> get-service sql* | format-list Name : SQLAgent$SQLEXPRESS DisplayName : SQL Server Agent (SQLEXPRESS) Status : Stopped DependentServices : {} ServicesDependedOn : {MSSQL$SQLEXPRESS} CanPauseAndContinue : False CanShutdown : False CanStop : False ServiceType : Win32OwnProcess Name : SQLBrowser DisplayName : SQL Server Browser Status : Stopped DependentServices : {} ServicesDependedOn : {} CanPauseAndContinue : False CanShutdown : False CanStop : False ServiceType : Win32OwnProcess Name : SQLWriter DisplayName : SQL Server VSS Writer Status : Stopped DependentServices : {} ServicesDependedOn : {} CanPauseAndContinue : False CanShutdown : False CanStop : False ServiceType : Win32OwnProcess
