Running the program you sent twice is exactly the same as just running
"/usr/bin/gksudo touch /bin/foo" twice. You've just wrapped it up in a
lot of Java.
Here is a fast and ugly hack (because I have never used ProcessBuilder
before) that will always ask for a password. It just calls "sudo -k"
before each call to gksudo. As was suggested in the very first answer to
your question.
Regards, K.
import java.io.BufferedReader ;
import java.io.InputStreamReader ;
public class test1
{
public static void main(String[] args) {
ProcessBuilder pb = new ProcessBuilder();
String comando = "";
try {
pb = new ProcessBuilder();
pb.redirectErrorStream(true);
comando = "/usr/bin/sudo -k";
pb.command("/bin/bash", "-c", comando);
System.out.println(comando);
Process p = pb.start();
BufferedReader output = new BufferedReader(new
InputStreamReader(p.getInputStream()));
String line;
while ((line = output.readLine()) != null) {
System.out.println(line);
}
int exitVal = p.waitFor();
System.out.println("exit code from \"sudo -k\"" + exitVal);
pb = new ProcessBuilder();
pb.redirectErrorStream(true);
comando = "/usr/bin/gksudo touch /bin/foo";
pb.command("/bin/bash", "-c", comando);
System.out.println(comando);
p = pb.start();
output = new BufferedReader(new
InputStreamReader(p.getInputStream()));
while ((line = output.readLine()) != null) {
System.out.println(line);
}
exitVal = p.waitFor();
System.out.println("exit code from \"gksudo\"" + exitVal);
} catch (Exception e) {
System.out.println(e.toString());
}
}
}
