This article explains Linux process states—including running, sleeping, disk sleep, stopped, dead, zombie, and orphan—detailing their meanings, kernel definitions, how to observe them with code examples, and the implications for system resource management.
This tutorial explains Linux process concepts, how to view and identify processes, the differences between programs and processes, and provides detailed examples of using fork, vfork, wait, exec family functions, system, and popen to create, control, and monitor child processes, including handling zombies and orphans.
This article explains the concepts of processes, their identifiers, the fork system call, and the differences between orphan and zombie processes, providing code examples, output analysis, and practical ways to handle each situation on Unix‑like systems.
This article explains Linux process fundamentals—including creation, the PCB, scheduling, and the emergence of zombie processes—details their causes and removal methods, and then compares processes with threads, covering multithreading implementation, issues, classifications, priorities, and synchronization techniques.
