09
Conditional Statements in Shell
In this lab, you will learn how to use conditional statements in shell programming to make logical decisions. You'll practice writing if-else statements, using elif for multiple conditions, performing numeric and string comparisons, and combining conditions with logical operators. By the end of this lab, you'll be able to create shell scripts that can make decisions based on various conditions.
10
Weather Advisory System
In this challenge, you'll develop a simple weather advisory system for a local meteorology office. Your task is to create a shell script that provides different advice based on the current temperature. This exercise will help you practice using conditional statements in bash scripting to handle various scenarios.
11
Bash Scripting Loops
In this lab, you will master the use of loops in Bash scripting. You'll learn how to implement for, while, and until loops to efficiently repeat instructions. Additionally, you'll explore break and continue statements to control loop execution. By the end of this lab, you'll be able to create more dynamic and flexible Bash scripts using various loop structures.
12
Comparing Arrays in Shell
In this lab, you will learn how to compare arrays in Shell scripting. You'll work with three arrays and implement a script to find common elements among them. This exercise will enhance your understanding of array manipulation, loops, and conditional statements in shell scripting.
13
Shell Functions
In this lab, you will learn about functions in shell programming. You'll create and use functions with parameters, explore return values, understand variable scope, and implement an advanced function. By the end of this lab, you'll be able to write reusable code blocks to perform repeated tasks efficiently in shell scripts.
14
Four Function Calculator
In this challenge, you'll create a basic four-function calculator using shell scripting. You'll implement functions for addition, subtraction, multiplication, and division, handling various scenarios including division by zero. This exercise will help you practice function definition, arithmetic operations, and error handling in bash scripting.
15
Special Variables in Shell
In this lab, you will explore special variables in shell scripting. You'll learn to use variables like $0, $1, $#, $?, and $$ to access script name, command-line arguments, argument count, exit status, and process ID. You'll also understand the difference between $@ and $* for handling multiple arguments.
16
Bash Trap Command
In this lab, you'll learn to use the Bash trap command to handle signals and interruptions in your scripts. You'll create a script that catches specific signals, implement custom actions for these signals, and use functions with trap for more organized code. By the end, you'll be able to write scripts that gracefully handle various scenarios and prevent unpredictable behavior.
17
File System Operations in Shell
In this lab, you will learn how to perform various file tests in the shell. You'll create test files and directories, check for their existence, and test file permissions. By the end of this lab, you'll be able to write shell scripts that can interact with the file system and make decisions based on file properties.
18
File System Explorer
In this challenge, you'll create a simple file system explorer script that demonstrates your understanding of basic file and directory operations in shell scripting. You'll implement functions to check the existence, type, and permissions of files and directories, enhancing your skills in file system manipulation and conditional testing in bash.
