Course Description
It’s important to understand processes in Linux because everything we do from the terminal is process oriented. A process is a program running in either the background or the foreground. There are two types of processes, parent and child, and many different commands that can be used to run them. If a process is interrupted, it generates a signal, which can indicate either a serious issue or something that doesn’t necessarily need to be addressed, so it’s imperative to recognize the difference. It’s also imperative to know how to properly shut down Linux, since it’s possible to damage the file system if it’s not shut down correctly. In these lessons, you’ll learn about the types of processes and process-related commands in Linux, as well as signals, how they work together, and how to manage them. You’ll also learn how to shut down the system.
Learning Objectives:
- Know the types of processes
- Recognize the signals and what they indicate
- Understand how to shut down the system
Skills You Will Learn
- Init Process
- Linux Commands
- Linux Programs
- Process Lifecycle
- Process Sequencing
- Unit Processes
What You'll Learn
- Identify the types of processes in Linux, including parent and child processes
- Run processes in the foreground and background using process-related commands
- Recognize signals and interpret what they indicate when a process is interrupted
- Distinguish between serious signal issues and those that do not require action
- Shut down the Linux system properly to avoid damaging the file system
Key Takeaways
- In Linux, everything done from the terminal is process oriented, since a process is a program running in either the background or the foreground.
- There are two types of processes, parent and child, and many different commands can be used to run them.
- When a process is interrupted it generates a signal, which can indicate either a serious issue or something that does not necessarily need to be addressed.
- Shutting Linux down correctly is imperative because improper shutdown can damage the file system.
Frequently Asked Questions
What does this course cover?
It covers the types of processes and process-related commands in Linux, signals and how they work together and are managed, and how to shut down the system.
What lessons are included in this course?
The course includes four lessons: Processes and Their Types, Process-Related Commands, Signals, and Shutting Down the System.
What are the learning objectives?
By the end of the course you will know the types of processes, recognize the signals and what they indicate, and understand how to shut down the system.
What skills will I gain from this course?
You will build skills in the Init Process, Linux Commands, Linux Programs, Process Lifecycle, Process Sequencing, and Unit Processes.
Why is it important to understand Linux processes?
Because everything done from the terminal is process oriented, and it is important to recognize whether an interrupted process signals a serious issue and to shut down correctly to avoid damaging the file system.
