thanks for your suggestion....
i change the code but now it is giving error as /usr/bin/find incomplete syntax....but i am giving the right syntax....
please confirm whether the syntax is correct...
import java.io.*;
import java.util.*;
public class linux_java {
public static void main(String[] args) {
try {
//String command = "ls -alt";
String command = "find /data2/opt/jakarta-tomcat-4.1.24/webapps/Oa/BOG -type f -exec grep -sl 'Aggarwal' {} \\; 2>/dev/null";
///grep -l System test/*java
System.out.println(" the command is"+command);
final Process process = Runtime.getRuntime().exec(command);
InputStream is = process.getErrorStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line="";
System.out.println(" the BufferedReader is"+br.readLine());
while ((line = br.readLine()) != null) {
System.out.println(" the files are"+line);
} catch (Exception e) {
e.printStackTrace();
