I could launch a external process via $zf(-2).

However, this child process need to refer some shared libraries in RUNTIME,so I have to set up the proper paths to the environment variable LD_LIBRARY_PATH, is anyone know how to do this?

Thank for your help.

I needed to do exactly that for LibreOffice to work.

do $zf(-2, "unset LD_LIBRARY_PATH && your_cmd")

Here's an article about that.

Is there a way to know the process Id of the given $zf(-2) on the *nix platform?

I would like kill this process after some conditions satisfied (or if there is other way to kill the process without knowing its pid).

Thanks.

Please ask this as a separate question.
What, and from where do you want to kill? Why? Consider expanding your question.
