This document provides a historical and technical overview of UNIX, from its inception in Bell Laboratories on PDP machines through its evolution involving multiprocessing, the C language, and real-time capabilities. It details UNIX system architecture, including the kernel, shell interactions, and the hierarchical file system's structure and permissions management. The document elaborates on process management, scheduling policies like round-robin and priority-based systems, and system calls used for process creation, execution, and termination. Additionally, it introduces I/O management,...
The document introduces the foundational concepts of operating systems, focusing on process management and execution. It defines processes as dynamic entities tied to program execution, describing their representation through Process Control Blocks (PCB) with critical attributes like PID, state, and priority. Process schedulers are analyzed, with an emphasis on the GNU/Linux round-robin method and distinctions between system and user processes. The dual modes of execution—user and kernel—are compared, alongside the introduction of associated commands like 'ps' and input-output redirection.
This document consists of three exercises focused on Linux system administration tasks. The first exercise involves the management of processes, including launching, pausing, and killing processes using commands like 'mousepad', 'top', and 'killall'. The second exercise emphasizes file content manipulation and redirection using commands like 'cat', 'wc', and 'sort', including handling errors and outputs. The third exercise centers on file searching and pattern matching in the /etc directory using advanced shell utilities like 'find' and 'xargs'. These exercises collectively enhance the user...
Ce document traite de la synchronisation et de la communication entre processus dans les systèmes d'exploitation.
