	Start a program in background, so you can continue using the shell while it's running. Whenever you start a program with the '&' operator appended, it will be assigned a job number which is displayed in square brackets. You can use this job number to bring the program back into foreground by invoking 'fg jobnumber'. To get the job into background again, you can use 'Ctrl-Z' to interrupt the program and 'bg jobnumber' to continue in background.

	In unix systems, the two possible values of boolean logic, TRUE and FALSE, are represented by 0 for TRUE and any other number than 0 for FALSE. This can be useful since every program has a return value which indicates, if the program ran successful or not. The return value of a successfully ran program will always be 0 which also means TRUE. Knowing this, we can for example use the success or fail of a program to determine if we want to run another program automatically.
