    Hi,

    I don't seem to get any results from the following use
    of Runtime.getRuntime().exec(cmd) using Java 1.4 on
    Redhat linux.

    Suppose that in the same directory as my java file below,
    I have files junk1, junk2, junk3, and i want
    to have the java program delete all of these files.

    However, when I run the following code,
    no deletion occurs.
    What am I doing wrong? 

    ---
import java.lang.Runtime;
import java.io.*;
public class Commandline
{
	String[] cmd = { "rm", "-f","junk*"};
//      String[] cmd = { "/bin/sh","rm", "-f","junk*"}; //doesn't work either
	public Commandline()
	{
		try
		{
			Process pro = Runtime.getRuntime().exec(cmd) ;
		}catch (IOException e)
		{
				System.err.println("ioexception starting process! " + e);
		}
	}
	public static void  main (String [] args)
	{
		Commandline c = new Commandline();
	}
}
