Saves command output in a file or variable, and displays it in the console.

Syntax

  Copy Code
Tee-Object [-FilePath] <string> [-InputObject <psobject>] [<CommonParameters>]

Tee-Object -Variable <string> [-InputObject <psobject>] [<CommonParameters>]

Description

The Tee-Object cmdlet sends the output of a command in two directions (like the letter "T"). It stores the output in a file or variable and also sends it down the pipeline. If Tee-Object is the last command in the pipeline, the command output is displayed in the console.

Parameters

-FilePath <string>

Specifies the file where the cmdlet stores the object. Accepts wildcards that resolve to a single file.

<CommonParameters>

This command supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, OutBuffer, OutVariable, WarningAction, and WarningVariable. For more information, see about_CommonParameters.

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.

Example 1

  Copy Code
C:\PS>get-process | tee-object -filepath C:\Test1\testfile2.txt 

Handles  NPM(K)	PM(K)	WS(K) VM(M)   CPU(s)	Id ProcessName
-------  ------	-----	----- -----   ------	-- -----------
   83	 4	 2300	 4520	39	 0.30	4032 00THotkey
  272	 6	 1400	 3944	34	 0.06	3088 alg

Description

-----------

This command gets a list of the processes running on the computer and sends the result to a file. Because a second path is not specified, the result will be displayed in the console.

Example 2

  Copy Code
C:\PS>get-process notepad | tee-object -variable proc | select-object processname,handles 

ProcessName							Handles
-----------							-------
notepad								43
notepad								37
notepad								38
notepad								38

Description

-----------

This command gets a list of the processes running on the computer and sends the result to a variable named "proc". It then pipes the resulting objects along to Select-Object, which selects the ProcessName and Handles property. Note that the $proc variable includes the default information returned by Get-Process.
