hi i am using this code to execute os command
import java.io.File;
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class RunSystemCommand {
public static void main(String args[]) {
String s = null;
// system command to run
String cmd = "copy a.txt b.txt";
// set the working directory for the OS command processor
File workDir = new File("c:
temp");
try {
Process p = Runtime.getRuntime().exec(cmd, null, workDir);
int i = p.waitFor();
if (i == 0){
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
// read the output from the command
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
}
}
else {
BufferedReader stdErr = new BufferedReader(new InputStreamReader(p.getErrorStream()));
// read the output from the command
while ((s = stdErr.readLine()) != null) {
System.out.println(s);
}
}
}
catch (Exception e) {
System.out.println(e);
}
}
}
