    Hi again,

    I tried:
    String[] cmd = { "/bin/rm", "-f", "junk*" };

    with:
    Runtime.getRuntime().exec(cmd) ;

    and still no luck.

    I even tried sticking the command "rm -f junk*" in
    an executable file "script.scr" and calling
    the java file containg the lines:
    Runtime.getRuntime().exec(cmd)
     where
    String cmd ="./script.scr".

    Nothing happened as well.

    I use "rm" as an example.
    I may need to call other applications, such as "/sbin/shutdown".

    Thanks again in advance.
