Project

A major part of this course is a collaborative software project, in which student groups design and construct a user-facing application involving multiple software components that communicate across a network.

Lectures

Files, editing, and shells

• Multiuser and multiprocess operating systems
• CLI basics (e.g., Bash)
• Unix file system organization
• Basic shell commands: ls; pwd, cd, mkdir, rmdir; echo, cat; cp, mv, ln, rm; chmod, kill, ps, grep, find

Commands and basic scripting

• The Unix shell as a scripting language
• Pattern matching, wildcards and regular expressions
• More advanced commands (e.g., grep, find)
