When I run a program from the console, e.g.

me@box:~$ firefox

I expect the console to log error messages (I think this is std out or std err?) and other items from the program, firefox in this case.

But today I notice that bash just opens the program and goes to a new prompt, e.g.

me@box:~$ firefox

How do I launch a program from bash such that error messages will be written to the console?

Why is it that some programs operate this way by default and others (firefox) do not?
