Any program you execute in a Linux shell spawns a new process that is identifiable using a process name and a Unique Process ID. In this article, we will focus on job control commands, allowing you to send processes in the background and bringing the bac

While Linux will handle the low-level, behind-the-scenes management in a process’s life-cycle – i.e., startup, shutdown, memory allocation, and so on – you will need a way of interacting with the operating system to manage them from a higher level. ...
