Managing Processes: `kill`, `bg`, `fg`

In Linux, every running program is called a process. Managing these processes is essential for system efficiency and troubleshooting.

This lesson teaches you how to take control of processes: suspending them, sending them to the background, bringing them forward, and even terminating them when they misbehave.

The kill command is used to send signals to processes. Its primary use is to terminate processes.

To use kill, you need the Process ID (PID) of the target process. You can find PIDs using commands like ps (covered in a previous lesson).
