I don't really know where this fits, so posting here. :)

How do i execute a command one would normally execute from the terminal? I did some googling, but i can't get it to work (nothing happens).

What i want execute:

Java Code:

"streamer -t 01:00:00 -j 100 -o pic.jpeg"

which you can execute directly from the terminal.

On a seperate note, how do you find out the host operating system?

ProcessBuilder. What have you tried and what happened when you tried that?

OS name, architecture and version can be obtained with System.getProperties().

Thanks,

I've made some progress, and have gotten a command to execute. The line is:

Java Code:

p = Runtime.getRuntime().exec(new String[]{"/bin/sh", "-c","streamer -r 30 -j 100 -t 01:00:00 -o "+workDir+"000000.jpeg"});

Now, my problem is this:

When the user exits the program, i must be able to stop the streamer process. p.destroy() simple quits the interpreter, sh. However, streamer continues to run. How do i end that process?
