Requirements / Prerequisites
- Basic Computer Proficiency: A fundamental understanding of navigating file systems, managing folders, and using standard applications is all that’s required to start.
- No Prior Programming Experience: This course assumes absolutely no background in coding, making it perfect for complete beginners looking to enter the world of scripting.
- Access to a Unix-like Environment: You will need a Linux operating system (like Ubuntu, Fedora), macOS, or Windows Subsystem for Linux (WSL) running on your computer to practice the commands and scripts.
- A Text Editor: Any basic text editor (e.g., Nano, Vim, VS Code, Sublime Text, Notepad++) capable of saving plain text files will suffice for writing your Bash scripts.
- An Open Mindset: A willingness to learn, experiment, and troubleshoot independently will greatly enhance your learning experience and retention of the material.
- Stable Internet Connection: Required for accessing the course materials and any supplementary online resources or documentation.
- Terminal Emulator: Familiarity with opening and interacting with your system’s terminal or command prompt is beneficial, though basic usage will be covered.
- Commitment to Practice: The most crucial prerequisite is the dedication to actively follow along with examples and apply the concepts to your own mini-projects.
Skills Covered / Tools Used
- Script Construction Fundamentals: Mastering the essential syntax for writing executable Bash scripts, including shebang lines and basic command sequencing.
- Variable Manipulation: Declaring, assigning, and utilizing variables to store data, manage paths, and customize script behavior dynamically.
- Conditional Logic: Implementing if, elif, and else statements to introduce decision-making capabilities into your scripts based on various criteria.
- Iterative Processes (Loops): Employing for and while loops to automate repetitive tasks, process lists of items, or perform actions until a condition is met.
- Input/Output Redirection: Directing standard output and error streams to files, and accepting input from files or other commands using redirection operators like >, >>, <, and pipes |.
- Function Definition and Usage: Creating reusable blocks of code within your scripts to improve modularity, readability, and maintainability.
- Basic Debugging Techniques: Learning how to identify and resolve common errors in Bash scripts using tools like set -x and careful script structure.
- Text Processing Utilities: Introduction to powerful command-line tools like grep for pattern searching, sed for stream editing, and awk for complex text analysis, pivotal for advanced automation.
- File System Operations within Scripts: Programmatically creating, deleting, moving, copying, and listing files and directories, extending beyond basic manual commands.
- Process Control: Understanding how to start background processes, bring them to the foreground, and manage their execution using commands like &, jobs, and fg.
- Exit Status Handling: Interpreting return codes (exit statuses) of commands to build robust scripts that react appropriately to success or failure.
- Shell Expansions: Grasping concepts like pathname expansion (globbing), brace expansion, and command substitution to write more flexible and powerful scripts.
- Environment Variable Management: Understanding the role of environment variables and how to set, unset, and utilize them within your scripts and shell sessions.
- Permissions Management: Scripting the modification of file and directory permissions using chmod to secure and control access to resources.
- Tools Used: The Bash shell itself, standard GNU/Linux utilities (ls, cd, cp, mv, rm, cat, echo, find, xargs, etc.), and any preferred text editor.
