How can I redirect output to a text file and the console (cmd) window at the same time?

Powershell 2.0 comes with the Tee-Object cmdlet which does exactly that. If you're using Windows 7, it comes with Powershell 2.0 installed. If you're using an older version of Windows, Powershell 2.0 is available for download.

The benefit of Powershell is that it can run the commands that cmd can as well.

Example:

dir | Tee-Object -file c:\output\dir.txt

There's a good answer for an identical question on StackOverflow

In summary, find a Win32 port of the Unix tee command.

I have made a batch file tool for this:

@ECHO OFF
SETLOCAL
 SET Append=false 
IF /I "%~1]=="/a" ( SET Append=true & SHIFT )
IF "%~1"== "" GOTO help
IF "%~2"== "" GOTO help
 SET Counter=0 
FOR /F %%A IN ('DIR /A /B %1 2^>NUL') DO CALL :Count "%%~fA"
 IF %Counter% GTR 1 ( SET Counter= & GOTO Syntax ) 
 SET File=%1
 DIR /AD %File% >NUL 2>NUL
 IF NOT ERRORLEVEL 1 ( SET File= & GOTO Syntax ) 
 SET Y= 
VER | FIND "Windows NT" > NUL 
IF ERRORLEVEL 1 SET Y=/Y
 IF %Append%==false  (COPY %Y% NUL %File% > NUL 2>&1) 
 FOR /F "tokens=1* delims=]" %%A IN ('FIND /N /V ""') DO (
    > CON ECHO.%%B  
        >> %File% ECHO.%%B
 ) 
ENDLOCAL 
GOTO:EOF
 :Count 
SET /A Counter += 1
 SET File=%1 
GOTO:EOF
 :help
 ECHO.
 ECHO Display text on screen and redirect it to a file simultaneously ECHO Usage: some_command ^| TEE.BAT [ /a ] filename 
 ECHO. 
ECHO Where: "some_command" is the command whose output should be redirected
 ECHO "filename" is the file the output should be redirected to
 ECHO /a appends the output of the command to the file,
 ECHO rather than overwriting the file
 ECHO. 
ECHO Made by Wasif Hasan. Nov 2019
Usage: command | tee 

Usage:

command | tee [/a] filename

[/a] will append to the file instead of over writing.

Use Tee-Object to pipe to variable with the -variable switch then use the variable to output to screen how you would like

get-aduser -filter * -Properties Name, CanonicalName, LogonWorkstations | where { $_.logonworkstations -match "\D" } | Select Name, CanonicalName, logonworkstations | sort canonicalname | Tee-Object -variable Users | Export-Csv -Path ".\$($MyInvocation.MyCommand.Name.split(".")[0])__$(Get-Date -uformat "%Y-%m-%d_%I-%M-%S_%p").csv" -NoTypeInformation

    Welcome. This question is about the Command Prompt (CMD) not PowerShell. – I say Reinstate Monica Sep 6 '19 at 21:32
