Release/Reset PowerShell Buffer Size back to CMD Prompt

Paul Black · 12 Oct 2021

Good evening.

I have a Batch Script where I set the CMD Prompt Window to open FULL size using this . . .

Code:


if not "%1"=="max" start /max cmd /c %0 max & exit /b

Some of the Reports/Logs that I run uses PowerShell Commands. I set the Buffer Size to the following so that the FULL OUTPUT gets written to the Report/Log. The thing is, when the Commands exits, it mucks up the CMD Prompt Window. It does NOT happen when I use PowerShell Commands on their OWN, it ONLY happens when I use PowerShell Commands with the following line . . .

Code:


PowerShell $Host.UI.RawUI.BufferSize = New-Object Management.Automation.Host.Size(250,1000)

How do I Release/Reset the PowerShell Buffer Size so it returns to what it was previously in the CMD Prompt Window.

I have obviously tried mode: etc.

I use the PowerShell Commands [ although I am NOT up with PowerShell, hence the request for help ] because it is more flexible and gives better Results and Output. I do NOT want to find a workaround using the Command Line because I have already been through that process, hence why I am using PowerShell.

Thanks.

OK, this problem might NOT be directly connected to PowerShell, although an answer to my above question would be nice.

After a LOT of time troubleshooting, I have narrowed the weird behaviour down to TWO echo. in the code.

Here is the test file. If you run the code you will see what I mean. I have quoted the TWO lines and the operation needed to make it work . . .

Code:


@echo off
if not "%1"=="max" start /max cmd /c %0 max & exit /b

setlocal EnableDelayedExpansion
set "Params=%*"
cd /d "%~dp0" && ( if exist "%Temp%\getadmin.vbs" del "%Temp%\getadmin.vbs") && fsutil dirty query %SystemDrive% 1>nul 2>nul || ( echo Set UAC = CreateObject^("Shell.Application"^) : UAC.ShellExecute "cmd.exe", "/k cd ""%~sdp0"" && %~s0 %Params%", "", "runas", 1 >> "%Temp%\getadmin.vbs" && "%Temp%\getadmin.vbs" && Exit /b)
%windir%\system32\reg.exe query "HKU\S-1-5-19" 1>nul 2>nul || ( echo. & echo  ERROR: This Batch file MUST be run in an ELEVATED cmd prompt [ Administrator ] & echo. & echo         Right-click the Batch file and click ^<Run as Administrator^>. & echo. & echo ^>Press ANY key to EXIT . . . & pause >nul & Exit )

set "DT=HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders"
for /f "usebackq tokens=3" %%X in (`Reg Query "%DT%" /V Desktop`) do (set Desktop=%%X)
for /f "usebackq delims=" %%X in (`echo "%Desktop%"`) do (set "Desktop=%%X")
set "Desktop=%Desktop:~1,-1%"

Set "Folder_Name=Sys_Reports"
set "DT_Folder=%Desktop%\%Folder_Name%"

set "LOG_01=Appx_Packages_Current_User"

:Options

set "Input= "

AFTER you have run Option 1, if you scroll down, you will see an EXTRA
>Enter an Option and press <Enter>:. As you scroll down further, it remains the last line on the screen.

I wonder if it is ME, or if there really is a problem!

I am NOT interested in adapting or modifying the code, just WHY this is an issue please.

Thanks.

EDIT:

I have just run this on another computer and it is fine. Maybe it is a problem with my Desktop, which is LONG OVERDUE for a Reinstall. Out of curiosity, I would be interested if the issue happens to ANYONE else though. I have NEVER had this issue before.
