如何执行包含双引号的PowerShell命令

Question

I'm trying to execute a PowerShell command (from JavaFx) to obtain a device driver version.

My problem is some double quotes included in the PS cmdlet.

Running the command

Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion | where {$_.devicename -like "*selectedDeviceName*"} Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion | where {$_.devicename -like "*selectedDeviceName*"} ,

directly in PS gives me the result I'm expecting to get. But (after numerous trial & errors and googling) I'm confused about how to handle the double quotes included in the cmdlet.

Here is the JavaFx method in which the PS cmdlet is embedded:

public void getDriverVersionViaPowerShell() {

ProcessBuilder psProcessBuilder = new ProcessBuilder("/Windows/System32/WindowsPowerShell/v1.0/powershell.exe",

"Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion| where {$_.devicename -like "*selectedDeviceName*"}");


//some code...
}

The "*selectedDeviceName*" part is my problem. selectedDeviceName is a string variable that contains the name of the device whose driver version I'm trying to get.

I would be glad to get some help to resolve this issue.

Thank you in advance for your time and help !!!

"Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion| where {$_.devicename -like \"" + selectedDeviceName +"\"}"

You can use \\ as escape character for including double quotes in string. Output would be:

Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion| where {$_.devicename -like "name of the driver"}
