I have a PowerShell Command which I need to execute using Java program. Can somebody guide me how to do this?
My command is Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate |
Format-Table –AutoSize
You should write a java program like this, here is a sample based on Nirman's Tech Blog, the basic idea is to execute the command calling the PowerShell process like this:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class PowerShellCommand {
public static void main(String[] args) throws IOException {
//String command = "powershell.exe your command";
//Getting the version
String command = "powershell.exe $PSVersionTable.PSVersion";
// Executing the command
Process powerShellProcess = Runtime.getRuntime().exec(command);
// Getting the results
powerShellProcess.getOutputStream().close();
String line;
System.out.println("Standard Output:");
BufferedReader stdout = new BufferedReader(new InputStreamReader(
powerShellProcess.getInputStream()));
while ((line = stdout.readLine()) != null) {
System.out.println(line);
}
stdout.close();
System.out.println("Standard Error:");
BufferedReader stderr = new BufferedReader(new InputStreamReader(
powerShellProcess.getErrorStream()));
while ((line = stderr.readLine()) != null) {
System.out.println(line);
}
stderr.close();
System.out.println("Done");
}
}
In order to execute a powershell script
String command = "powershell.exe \"C:\\Pathtofile\\script.ps\" ";
.ps1 file contains a space, you can modify the command to: String command1 = "powershell.exe & 'C:/test folder with spaces/yourPowershellScript.ps1' "; to run the script from eclipse.
-and or -or between your commands to connect them.No need of reinvent the wheel. Now you can just use jPowerShell. (Disclosure: I am the author of this tool.)
String command = "Get-ItemProperty " +
"HKLM:\\Software\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\* " +
"| Select-Object DisplayName, DisplayVersion, Publisher, InstallDate " +
"| Format-Table –AutoSize";
System.out.println(PowerShell.executeSingleCommand(command).getCommandOutput());
you can try to call the powershell.exe with some commands like :
String[] commandList = {"powershell.exe", "-Command", "dir"};
ProcessBuilder pb = new ProcessBuilder(commandList);
Process p = pb.start();
You can use -ExecutionPolicy RemoteSigned in the command.
String cmd = "cmd /c powershell -ExecutionPolicy RemoteSigned -noprofile -noninteractive C:\Users\File.ps1
