We delved into the history of Linux, exploring its origins, development milestones, and the philosophy behind open-source software.
- Origins and evolution of Linux.
- Key milestones in Linux development.
- Philosophy and principles of open-source software.
Understanding the command line interface is fundamental to working with Linux-based embedded systems. We learned how to navigate the command line efficiently and explored the build process for compiling and linking software applications.
- Navigating the command line.
- Commonly used command line commands.
- Build process for compiling and linking applications.
Understanding the concept of processes in Linux and how they interact with the operating system.
Exploring system calls and their role in process management, along with handling command line arguments in C programs.
Learning about process creation using functions such as fork() and exec().
Understanding the concepts of orphan and zombie processes and their implications on system resources.
Exploring advanced features of the Bash shell for scripting and automation.
Introduction to the /proc filesystem and its role in providing information about processes and system resources.
Mastering input/output redirection techniques in the shell for efficient command-line usage.
We covered user management concepts, including user account administration, permissions, and security practices.
- User account administration.
- Managing permissions and access control.
- Security practices for user management.
Understanding hard disk drive (HDD) fundamentals and their role in storing data on embedded systems.
Exploring Master Boot Record (MBR) partition tables and techniques for parsing them.
Learning about file system formats, mounting procedures, and the underlying architecture of file systems.
Understanding the structure of directories and files, symbolic and hard links, and managing permissions for file access control.
Developing a simplified version of the ls command to list directory contents.
This training provided a solid foundation in Linux systems programming, covering essential topics and practical skills. For further reading and practice, consider exploring the following resources:
