Beginning Linux programming (Neil Matthew, Richard Stones) (Z-Library)

【One-Line Pitch】 A practical, tutorial-driven guide that takes you from compiling your first C program to building GUI apps and networked services on Linux, ideal for programmers who learn best by doing rather than by reading theory. 【Book Arc】 - **Opening (~0%–5%)**: Sets up the book's "learn by doing" philosophy and covers the absolute basics — getting your development environment ready, compiling programs, and linking to libraries. This stage solves the "where do I even start?" problem for newcomers. - **Early (~5%–25%)**: Dives into shell programming and file handling, teaching you to automate tasks and manipulate data at the system level. This is the foundation for understanding how Linux treats everything as a file. - **Middle (~25%–50%)**: Explores the Linux environment, terminal I/O, and text-based screen management with curses. You'll learn to write interactive programs that respond to user input and manage data effectively, including an introduction to MySQL for persistent storage. - **Late (~50%–75%)**: Shifts to professional practice — development tools, debugging techniques, and the core of system programming: processes, signals, POSIX threads, and inter-process communication via pipes, semaphores, shared memory, and message queues. - **Ending (~75%–100%)**: Covers network programming with sockets, then moves up the stack to GUI development with GTK+ (GNOME) and Qt (KDE), finishing with a look at Linux standards. This stage ties everything together into full application development. 【Key Takeaways】 - **Compilation and linking are the gateway to Linux programming** (Early): Understanding how to compile C code and link against libraries is non-negotiable; the book walks you through it step by step, so you're never left guessing about build errors. - **Shell scripting is your automation superpower** (Early): Before writing complex C programs, you'll learn to script common tasks — a skill that pays off daily for system administration and rapid prototyping. - **The Linux environment is your API** (Middle): Environment variables, terminal control, and file descriptors aren't just background noise; they're the tools you'll use to make your programs behave correctly in different contexts. - **curses turns text terminals into interactive UIs** (Middle): If you need a menu-driven or full-screen text interface, the curses library is your answer — the book shows how to manage screen layout and user input without a GUI. - **Data persistence matters early** (Middle): The MySQL chapter isn't an afterthought; it teaches you to store and retrieve structured data, a requirement for almost any real-world application. - **Debugging is a skill, not a chore** (Late): The dedicated debugging chapter covers tools and techniques that will save you hours — learning to use a debugger properly is as important as writing the code itself. - **Processes and threads are the heart of system programming** (Late): From signals to POSIX threads, you'll understand how Linux manages concurrent execution, and how to write programs that handle multiple tasks safely. - **IPC and sockets connect everything** (Late–Ending): Pipes, shared memory, and sockets are how Linux programs talk to each other — locally or across a network. This is where the book moves from "programming" to "building systems." 【Reading Tips】 - **Skim the first two chapters if you're already comfortable with C and the command line** — the real value starts with file handling and the Linux environment. - **Deep-read the debugging and process/thread chapters** — these are the hardest to learn from documentation alone, and the step-by-step examples here are worth the time. - **Treat the MySQL and GUI chapters as reference material** unless your project specifically needs them — they're well-written but skimmable if you're focused on system programming. - **Do the exercises** — the book's "learn by doing" approach means the examples are deliberately incremental; skipping them will leave gaps in your understanding. - **Watch for the standards chapter at the end** — it's easy to skip, but it explains why Linux APIs look the way they do, which helps when you encounter platform-specific quirks. 【Coverage Limits】 This guide is based on the table of contents and introductory material; detailed content from individual chapters (e.g., specific code examples, API signatures, or debugging walkthroughs) is not covered here.
