How to fire top+grep command using java on Linux

[Swapnil Ayachit]

I am facing problem while executing top command on Linux.
I am using java 1.4.2 .
The below program works fine on Solaris but is not excuting properly on linux enterprise version.
The program gets complied but after executing it, I am not getting output of top command in the file.

public class Test 
{
Test()
{
        }
public static void main(String args[])
{
String temp=null;

try{
Float cpu;
String str[]=new String[]{"/bin/bash","/usr/bin/top -b -n 1| grep a.out | awk '{print $11}' > temp_cpu"};
 
Process p = Runtime.getRuntime().exec(str);

        FileReader fr = new FileReader("temp_cpu_2"); 
BufferedReader br = new BufferedReader(fr);
temp=new String();

while((temp = br.readLine())!= null) 
{ 
cpu=new Float(temp);
System.out.println("cpu is : " + cpu);
}
fr.close(); 
}catch(Exception e){ }
}
}

Welcome to JavaRanch, Swapnil Ayachit!

When posting code, please be sure to surround the code with the [code] and [/code] UBB Tags. This will help to preserve the formatting of the code, thus making it easier to read and understand.

Could you describe what "not excuting properly on linux" means?
