Windows 7: How to execute Powershell command from CommandPrompt? One line!

pstein · 30 Oct 2019

I want to execute a PowerShell command from Command Prompt.
This should be done by entering ONE command!

I DO NOT want to start PowerShell first and then enter the PowerShell command.

Instead I want to enter something like

powershell.exe -command "......."

How does that work in detail on Win7?

What do you want the command to produce?

Hi pstein,

If you wanted to get the bit-type of your OS for example, you could use this in the cmd prompt . . .

Code:

Powershell -Command (Get-WmiObject Win32_OperatingSystem).OSArchitecture

You could also use that in a batch script!

I hope this helps!

Why does

Powershell -Command {Get-HotFix | Sort InstalledOn -Desc}

NOT work?

When I enter this in CmdPrompt/Batch script then the output is:

"Input file specified two times."

Hi pstein, I do have a batch script that lists all the installed updates!

See Powershell /? for explanation.

You need to create a string that Powershell can execute, so in your case, type:

Powershell -Command "& {Get-HotFix | Sort InstalledOn -Desc}"

Obvious when you know how!!
