Nested processes

Hi,

Is there a way to use Runtime to run nested UNIX processes? For example, I would like to connect to a UNIX machine, then run a shell script on it. I have the following:

String connect ="ssh newUser@192.168.1.1";

String processToRun ="sh /home/newUser/test.sh";

Runtime rt = Runtime.getRuntime();

Process proc;

proc = rt.exec(connect);

proc = rt.exec(processToRun);

This, however, does not work. What happens is that it never terminates. What I believe happens is that once it executes the SSH command, the next SH command actually waits for SSH to terminate before it executes it. But then, the SSH process is, at the same time, waiting for a command. The thing is that I want the SH command to execute WITHIN the SSH process.

If I run this:

String connect ="ssh newUser@192.168.1.1";

String processToRun ="sh /home/newUser/test.sh";

Runtime rt = Runtime.getRuntime();

Process proc;

proc = rt.exec(connect +" " + processToRun);

This works ok because it is the same as simply running:

ssh newUser@192.168.1.1 sh /home/newUser/test.sh

right from UNIX which is ok. But this may be a problem if I want to run lots of processes within processes.

Can this be done?

Thanks!
