Right Angle Triangle Pattern

Greet User Based on Time

Bubble Sort Command-Line Sorting Shell scripting is the secret weapon of every efficient system administrator. Instead of manually repeating tasks, you can teach your computer to do the heavy lifting for you. This learning path is designed to take you from a command-line novice to a confident scripter through hands-on, interactive challenges that focus on real-world logic rather than boring theory. Difficulty: Beginner | Time: 5 minutes In this challenge, we will learn how to create a pattern using loops in a shell script. We will take input from the user and generate a pattern of numbers in the format mentioned in the problem statement. This will help us understand the working of loops in shell scripts and how to execute a bash script. Practice on LabEx → | Tutorial → Difficulty: Beginner | Time: 5 minutes In this challenge, we will create a script that greets the user based on the current time. We will use the date command to get the current time and then use cut and tr to extract the relevant information. We will also learn about bash configuration files and how to run a script as soon as we log-on to the system. Practice on LabEx → | Tutorial → Difficulty: Beginner | Time: 5 minutes Sorting is an essential operation in computer science that arranges data in a specific order. In this challenge, we will write a script that sorts a given set of numbers in ascending or descending order using the bubble sort algorithm. The script will take input from the user through command-line arguments and provide a menu for the user to choose the sorting order.
