Question

I tried to execute a multiple commands in a single command line prompt. Here i need to hide to directories. I used this command "C:\Windows\System32>cacls C:\Users\FSSD\Desktop\test1 /e /c /d %username% & cacls C:\Users\FSSD\Desktop\test3 /e /c /d %username% & cacls C:\Users\FSSD\Desktop\test3 /e /c /d %username%)"in commad prompt it executed well, when i use this code in my java Program it doesn’t work completely. The first command will be executed.

In my java code i used this command like this,

Runtime runtime = Runtime.getRuntime();
    try {
        Process process = runtime
                .exec("cmd.exe /c start cacls C:/Users/FSSD/Desktop/test1  /e /c /d %username%) " + "&"+            
                      "  cacls C:/Users/FSSD/Desktop/test2  /e /c /d %username%" +"&"+  
                      "  cacls C:/Users/FSSD/Desktop/test3  /e /c /d %username%");

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

in this what mistake i done, else any other possible to achieve this..

Answer 1

Why don’t you put that lengthy command into a .bat or .cmd file and invoke that file from Java?
