Linux - Run command as a background process

To run a command as a background process you must append & to the end of the command when issuing:

$ <command> &

If you wish the command to continue running even when you have logged off, you need to issue nohup at the beginning of the command:

$ nohup <command>

If you wish to run the command in the background even when you are logged off you should append with nohup and &:

$ nohup <command> &
