I have a command for diskpart -- run the script from a file myscript.txt in Powershell
diskpart /s myscript.txt
But when I execute this command through Powershell, it requesting permission to execute, then runs in a new window (this is cmd shell, not Powershell) and I cannot get its output.
Is it possible to get the output of this command and display it in the Powershell window?

I have a powershell script that runs an .exe tool.
& tool.exe
If I run the script from a cmd console, the exe output is not written through the cmd console...
C:\>powershell .\script.ps1
Insead, if I run the script from a Powershell console everything is alright.
Do you know how to make the exe output visible from the cmd console?
I think I resolved like this:
& tool.exe | Write-Host
It's not very smart, but it works...
There is a bat file in which a command (nqcmd) is executed. This command only executes, when we open the batch file as an administrator. Otherwise, an error comes.
I tried to run the batch file as administrator from powershell, like this,
powershell.exe -Command "start-process -filepath C:\foo.cmd -verb runas"
It opens two cmd windows - a normal cmd window, in which the batch file executes and an error comes:
'nqcmd is not recognized as an internal or external command, operable program or batch file',
and an administrator's cmd window.
But, in this window, that batch file does not executes. We have to type the batch file's name again and then it executes.
I wanted to ask that, in a separate batch file, can we take that instance of administrator's cmd window and then run commands in it, without manually typing in that window?
Thank you.
I am having a bunch of issues with getting a PowerShell command to run. All it is doing is running a command that would be run in a CMD prompt window.
Here is the command:
"C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe" PCNAME
I have tried the following with no success (I have tried many iterations of this to try and get one that works. Syntax is probably all screwed up):
$TEXT = $textbox.Text #$textbox is where the user enters the PC name.
$CMDCOMMAND = "C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe"
Start-Process '"$CMDCOMMAND" $TEXT'
#iex -Command ('"C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe"' $TEXT)
The command will just open SCCM remote connection window to the computer the user specifies in the text box.
Try this:
& "C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe" PCNAME
To PowerShell a string "..." is just a string and PowerShell evaluates it by echoing it to the screen. To get PowerShell to execute the command whose name is in a string, you use the call operator &.
To run or convert batch files externally from PowerShell (particularly if you wish to sign all your scheduled task scripts with a certificate) I simply create a PowerShell script, e.g. deletefolders.ps1.
Input the following into the script:
cmd.exe /c "rd /s /q C:\#TEMP\test1"
cmd.exe /c "rd /s /q C:\#TEMP\test2"
cmd.exe /c "rd /s /q C:\#TEMP\test3"
*Each command needs to be put on a new line calling cmd.exe again.
This script can now be signed and run from PowerShell outputting the commands to command prompt / cmd directly.
It is a much safer way than running batch files!
One solution would be to pipe your command from PowerShell to CMD. Running the following command will pipe the notepad.exe command over to CMD, which will then open the Notepad application.
PS C:\> "notepad.exe" | cmd
Once the command has run in CMD, you will be returned to a PowerShell prompt, and can continue running your PowerShell script.

CMD's Startup Message is Shown
As mklement0 points out, this method shows CMD's startup message. If you were to copy the output using the method above into another terminal, the startup message will be copied along with it.
For those who may need this info:
I figured out that you can pretty much run a command that's in your PATH from a PS script, and it should work.
Sometimes you may have to pre-launch this command with cmd.exe /c
Examples
Calling git from a PS script
I had to repackage a git client wrapped in Chocolatey (for those who may not know, it's a package manager for Windows) which massively uses PS scripts.
I found out that, once git is in the PATH, commands like
$ca_bundle = git config --get http.sslCAInfo
will store the location of git crt file in $ca_bundle variable.
Looking for an App
Another example that is a combination of the present SO post and this SO post is the use of where command
$java_exe = cmd.exe /c where java
will store the location of java.exe file in $java_exe variable.
You must use the Invoke-Command cmdlet to launch this external program. Normally it works without an effort.
If you need more than one command you should use the Invoke-Expression cmdlet with the -scriptblock option.
I am very new to powershell and sometimes this question may be so simple
Can please anybody please tell me what is the equivalent to the following(vbscript) in PowerShell
set obj = wscript.createobject( wscript.shell )
Obj.Run $smCmnd
What is the use of wscript.shell.
After a bit of search I found first line can be presented as;
$obj = New-Object -ComObject WScript.Shell
But have have no idea how to call Run method ($obj.run(...)???)
If I run cmd.exe with some commands as the smCmnd, How can I keep cmd.exe without close and to run another command later in same console??
EDIT
I am writing PS script and it will be call from another application. Basically it will do some folder creations and file coping etc. I would like to open CMD.exe and show all the commands running on that. How to use same cmd prompt through out my whole script.
Is smCmnd a string of shell commands? If so, you can call them directly from PowerShell, without trying to get a wscript.shell COM object to run them against like you'd need to do in VBScript.
VBScript wasn't a shell. Powershell is. You can write shell commands directly in .ps1 or .ps2 files, just like in a batch file.
I'm not a powershell expert here, but try doing
& $smCmnd
Try running $smCmnd directly. If that fails, use Invoke-Expression $smCmnd.
If you do need to use CMD.EXE (possibly because you want to run pre-existing BAT file), and you want all of the output in a single CMD window you can pipe all the input into cmd at once like this:
# Powershell script to execute existing BAT file
cmd.exe /k "cd c:\batchfiles & firstone.bat & second.bat & echo that's all folks"
# CMD will remain open (/k). User will have to type exit to return to powershell
# Or if you want user just to hit any key to leave CMD prompt:
cmd.exe /c "c:\batchfiles\mybatchfile.bat & pause"
# /C means CMD should close after is has executed the commands on the command line
However if you want to have something execute in CMD, then make a decision in your Powershell script about what to execute next in CMD then do something similar to the answer at the following link which pipes input and output between a powershell script and CMD.exe.
How to run interactive commands in another application window from powershell
so i have a bat file that goes:
powershell -noexit "My\file\location\myscript.ps1"
the bat file is in the start up. the powershell script changes the bcd. when executed in this manner it says i do not have privileges, access denied, and nothing in the bcd is changed.
sorry for being a newb, but is there a way to pass an elevated privileges value from the bat to the powershell script?
I don't know if this is possible to do from outside Power Shell but it can be done from inside. It's hacky but you could run a power shell script from your bat file that then launches the admin Power Shell session using "PS> Start-Process powershell -Verb runAs".
