Overview:
The Linux system programming workshop is designed to be a completely hands on workshop to address the need of professionals who would like to move to Linux/Unix for development or QA related activities from any other OS platform. It is also useful for those who have done some work on any Unix flavour and feel the need to develop a solid understanding of the operating system and system programming related concepts on Linux.
This course aims at developing a comprehensive understanding of the Linux system programming aspects with emphasis on the following areas:
- Overview and structure
- Development environment – compiling, linking, creating shared libraries
- Working of system calls on Linux
- Detailed understanding of file, process and memory management
- Inter-process communication and signal handling
- Multi-threading and thread synchronization
- Logging
- Debugging
Takeaways from Workshop:
- Develop good understanding of Linux operating system concepts and development environment
- Exhaustive hands-on coverage on every area aimed at making participant ready for independent software development/QA •
- Understanding key tools and resources available on Linux
Target Audience:
- Developers/Designers, Senior Developers/Designers
- Technical/Engineering or Project Managers who need a good technical background of any Unix/Linux
- Technical Leads, QA Leads and QA Engineers who plan to work on Unix/Linux systems
- Anyone who wishes to develop a good understanding of the workings of Unix/Linux OS
Pre-requisite
- C coding on any platform
- Some familiarity using any flavour of Unix/Linux. Knowledge of some basic shell commands like listing files, starting processes, using cat, grep etc. Refer pre-requisite doc for more information.
Delivery Method:
Instructor lead and hands on. The course has a heavy emphasis on hands on coding for almost every topic of the presentations.
