Nothing is returned to the Windows PowerShell console:Ĭopy-Item -path C:\fso\a.txt -Destination C:\fso31 In the following command, I copy the a.txt file from the c:\fso folder to the C:\fso31 folder. When I use the cmdlet to copy a file from one location to another location, nothing returns to the Windows PowerShell console. The commands and associated output are shown in the following figure.Īnother cmdlet that contains a passthru parameter is the Copy-Item cmdlet. $notepad = Start-Process notepad –PassThru I then examine the start time of the process, and finally I stop the process by piping the Process object to the Stop-Process cmdlet: In the following code, I store the returned Process object in a variable named $notepad. If I store the returned Process object in a variable, I can then use it to obtain additional information about the process. The command and associated object is shown in the following figure. The command to start the Notepad process and to return a Process object to the Windows PowerShell console is shown here: The nice thing about this is that I can use this Process object to track and work with the newly created instance of Notepad.

The resulting command is shown here (in the following command, gcm is an alias for the Get-Command cmdlet a commandtype of 8 is a cmdlet I use the ? as an alias for the Where-Object cmdlet): I then pipe the resulting cmdletInfo object to the Where-Object and look for matches on passthru. To find all of the Windows PowerShell cmdlets that have a passthru parameter, I use the Get-Command cmdlet. There are also two parameters that are available when a command will change system state (such as Start-Process, Stop-Process). First of all, passthru is not one of the common parameters, and it does not exist everywhere. Perhaps a few examples will show how it works. ML, you are right, the passthru parameter seems to be mysterious. They will have their first meeting in January.
