COURSE CONTENTS

Introduction to Unix/Linux and MTX Operating Systems:

• Files, directories, special files, logical organization of Unix file system; user account, login process and command execution.

Program Development:

• Source files; compiler, assembler and object files; linker, library and executable files; loader and execution images. Symbolic debugger and run-time support.

Execution Image of C Programs:

• Code, data and stack segments; function calling convention, stack frames and parameter passing; long jumps.

File I/O:

• System calls and low-level file I/O; open, close, read, write, lseek, file descriptors and file sharing. Execution of User mode and Kernel mode images, implementation and implications of system calls.

File Control:

• Permissions and access control, fcntl, chown, chmod, hard and soft links, file status and statistics. I/O redirection, pipes, filters and applications.

Standard I/O Library:

• Streams and high-level file I/O; user space buffering, relationship with low-level I/O, char and line mode I/O. Formatted I/O.

File System Implementation:

• Inodes and file representation; mkfs and physical file system layout; traversal of the file system tree; booting system images.

Processes:

• Concept and implementation of processes, process execution environment, user mode and kernel mode images, process states transitions. Processes in the Unix system; init, login and user processes.

Process Control:

• fork, vfork, wait, exit, kill, exec operations. traps and signal handling.
