Execute linux bash command and read its output from java Program

This is a very frequent snippet that you want and spend a lot of time researching on the basic technique. Following is the java code snippet.

	import java.io.BufferedReader;
	import java.io.IOException;
	import java.io.InputStreamReader;
	public class cmdExecute2 {
	public static void main(String[] args) {
	String osName = System.getProperty("os.name");
	String rawVersion = null;
	StringBuffer outputReport = new StringBuffer();
	String cmdToExecute = "awk '/Service.*DisplayGroupName.*Name.*ProductID/' /usr/local/services.conf";
	if (osName != null && osName.indexOf("Windows") == -1
	&& osName.indexOf("SunOS") == -1) {
	Runtime rt = Runtime.getRuntime();
	BufferedReader is = null;
	try {
	// execute the RPM process
	Process proc = rt.exec(new String[]{"sh","-c",cmdToExecute});
	// read output of the rpm process
	is = new BufferedReader(new InputStreamReader(proc.getInputStream()));
	String tempStr = "";
	while ((tempStr = is.readLine()) != null ) {
	outputReport.append(tempStr.replaceAll(">", "/>\n"));
	tempStr = "";
	}
	int inBuffer ;
	while ((inBuffer = is.read()) != -1) {
	outputReport.append((char) inBuffer);
	}
	// rawVersion = is.readLine();
	// response.append(rawVersion);
	is.close();
	proc.destroy();
	} catch (IOException ioe) {
	System.out.println("Exception executing command " + cmdToExecute + "\n" + ioe);
	} finally {
	try {
	is.close();
	} catch (final IOException ioe) {
	System.out.println("Cannot close BufferedStream" + ioe);
	}
	}
	}
	System.out.println(outputReport.toString());
	} // end of main
	} // end of class
