Linux top 50 cmd - Bg

The bg command is used to force a suspended process to run in the background. For example, you might have started a command in the foreground (without using & after the command), and realized that it was going to take a while, but that you still needed your shell. You could take that process that is currently running and hold down the Ctrl key, and, while it is held down, press the Z key. This places the current process on hold. You can either leave it on hold, just as if you called your telephone company, or you could place that process in the background by typing bg. This then frees up your shell to allow you to execute other commands.
