Thread: how best to run external process and control it

I have a Java standalone gui developed using eclipse Java EE.

Firstly I need to run a C executable with the command line similar to (it varies based on user input) this:

String filePath = "nohup C:/Users/User/workspacejavatest2/t3drive.exe -v4 fred777 1 1 1 java2.msg > fred777.log 2>&1 &";
Process p = Runtime.getRuntime().exec(filePath);

First question is how best to ensure this is correctly escaped. Is there a uri type approach or is it a manual job?

Secondly I'd like to kill the process if something goes wrong. What is the best approach when this might be used on Linux, Windows, or whatever?

Just looking for guidance, not code, as don't want to do it the longway round if there is a slick approach. Many thanks for viewing and even more tx for any ideas

Thanks Kevin and Copeg. Very useful stuff and you have me off in the right direction. Already I can see that I can do what is required but just need to build a few examples and get familiar with it. Already have ProcessBuilder in a test environment and having fun. OK only dir todate but we all start somewhere.

As you say Copeg we can always shell to avoid pipes, and when not on our beloved linux we have cygwin so no need for any Windows stuff.

Cheers
