Names of binaries

[Peter Flynn]

Typically, in a GUI system interface, there is a "dock" or "panel" or
something with an icon for every user application that is executing.

Most of these are the result of the user having clicked on a menu entry
or a desktop icon.

Is there a way to find the name and location of the actual binary of the
application. I know you can list all processes with ps, but many
applications are run from a shell script, which calls a language
processor, which fires up a stub, which finally causes the app to run,
and sorting them out from ps ax can be tricky.
