====== BASH - Run a program or script - Run a program in the background ======

By default, programs usually run in the foreground.  This prevents another application being run in the same terminal at the same time.  

To have this first program run in the background:

Pause the running process by hitting **CTRL-Z**:

<code bash>
CTRL-Z
</code>

This will pause the running process.

returns:

<code>
^Z
[1]+  Stopped                 sudo ls -R /
</code>

<WRAP info>
**NOTE**:  From here you can manipulate it with:

  * **fg**:  Move to foreground
  * **bg**:  Run in background.
  * **kill**:  Kill the process.
</WRAP>

====== Restart the job in the background ======

<code bash>
bg
</code>

returns:

<code>
[1]+ sudo ls -R / &
</code>

<WRAP info>
**NOTE:**  The command is now running in the background.

We can now run the other application.
