Inputs and Outputs
The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet returns.
Inputs |
System.Management.Automation.PSObject You can pipe objects to be redirected to Tee-Object. |
Outputs |
System.Management.Automation.PSObject Tee-Object returns the object that it redirected. |
Notes
You can also use the Out-File cmdlet or the redirection operator, both of which save the output in a file but do not send it down the pipeline.
Tee-Object uses Unicode encoding when it writes to files. As a result, the output might not be formatted properly in files with a different encoding. To specify the encoding, use the Out-File cmdlet.
