Transitioning from a casual terminal user to a power user requires more than just memorizing commands; it requires the ability to weave those commands into powerful, automated scripts. Whether you are managing system resources or processing text, Shell scripting is your ultimate toolkit. In this guide, we explore three hands-on LabEx challenges designed to take you from basic syntax to practical system administration automation.
Right Angle Triangle Pattern
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.

Display Filesystem Free Space Utilization
Difficulty: Beginner | Time: 5 minutes
The freeSpace.sh script is designed to display the names of any file-system which have less than n% free space available. It makes use of the df, tr and cut commands to retrieve information about the file-systems present in the system and then filters out the ones that have less than n% free space remaining.

Print File Lines Using Bash Commands
Difficulty: Beginner | Time: 5 minutes
In this challenge, we will write a shell script to print the contents of a file from a given line number to the next given number of lines. We will use the head and tail commands to achieve this. The script will take three command-line arguments: the starting line number, the number of lines to print, and the filename.
