Unit 1: Introduction to Shell Scripting

• What is a shell script?

• Types of shells: bash, sh, etc.

• Setting up the development environment: Terminal emulators, text editors.

• Basic shell commands: ls, cd, mkdir, rm, cp, mv, echo, etc.

• Variables and data types: String, integer, and basic types.

• Writing and running simple scripts.

• Permissions and execution: chmod, shebang

Unit 2: Control Structures and Flow Control

• Conditional statements: if, else, elif.

• Comparison operators

• Logical operators

• Looping structures

• Break and continue statements.

• Case statements: switch-like behavior in shell scripts.

Unit 3: Input and Output Handling

• Reading user input: read command.

• Command line arguments

• Output redirection

• Pipes and filters: |, grep, awk, sed.

• Here documents: << syntax for multiline input.

Unit 4: Functions and Script Organization

• Defining and using functions.

• Passing arguments to functions.

• Return values from functions.

• Local and global variables.

• Modularizing scripts: breaking down large scripts into functions.

• Script organization best practices.

Unit 5: String Manipulation and Regular Expressions

• String concatenation and interpolation.

• String manipulation: length, substring extraction, searching.

• Regular expressions: basic syntax and usage.

• Pattern matching with grep, sed, and awk.

Unit 6: Advanced Topics

• Arrays: declaring, accessing elements, looping through arrays.

• Associative arrays (dictionaries): key-value pairs.

• File handling: reading, writing, appending.

• Exit status and error handling: exit codes, trap command.

• Advanced scripting techniques and tips.

Unit 7: Practical Projects

Unit 8: Projects and Assessment

• Students work on individual or group projects.

• Project presentations and code reviews.

• Assessment of scripting skills through practical tasks.

• Wrap-up and discussion on future learning paths.

• Remember, the actual duration of each unit may vary based on the pace of

the course and the level of expertise of the participants. Additionally,

practical exercises, assignments, and real-world examples should be

integrated throughout the course to reinforce learning
