a daemon thread is just an ordinary thread that has been set as a
daemon. their purpose is to be servant threads. when there are only
daemon threads left a program will exit.
as such, it executes in the same jvm instance as it's parent.
parent spawns daemon,
daemon spawns shell,
shell runs command to kill parent
which kills daemon
which kills shell which kills command.
just a big circle.
i don't know about other OS, but the process control features of the
bash shell on linux would allow what i think you are trying to achieve.
don't worry about needing a thread. just try something like
String command = "/where/your/script/lives/scriptname restart& disown";
getRuntime().exec(command);
regards,
Kevin
