hi all,
Is there any way that I can invoke an external program or shell command under unix? Thanks a lot.
Regards

Here's some code that I've used to run an executable and pass in command line arguments.

Runtime rt = Runtime.getRuntime();
Process prcs = rt.exec("/prd1/exe/udms mod 4rw salary gen con <infile.txt >/dev/null");
prcs.waitFor();

In this example, udms is the executable, the rest of it is command line arguments particular to this application. Hopefully this will help you get started. You're also going to have to handle IOException and InterruptedException.
Hope this helps.
