Is this transcript what you see?

There are several things going on here:
1. You type `ls&' and press return.
2. bash starts up the ls program and prints the job number ([1]) and
its process id number (15060). It then displays the prompt.
3. While this is going on, ls is reading the directory and sorting
it. It displays the directory list.
4. At the same time, bash is waiting for you to type a command. It
has already displayed the prompt. You can type a command now.
However, you press enter instead.
5. bash detects that the ls process is dead. It displays a message to
that effect.
6. bash displays another prompt.
Does that help?
