What does “&” at the end of a linux command mean?

http://stackoverflow.com/questions/13338870/what-does-at-the-end-of-a-linux-command-mean

The & makes the command run in the background.

From man bash:

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0.
