Transitioning from a casual Linux user to a power user requires more than just memorizing commands; it requires the ability to automate. Whether you are managing system configurations or streamlining daily tasks, Shell scripting is your most powerful ally. This learning path takes you through five hands-on challenges designed to turn you into a command-line pro, one script at a time.
Search User in System Configuration
Difficulty: Beginner | Time: 7 minutes
In this challenge, we will write a script to search for a user present in the system. We will fetch the usernames from the /etc/passwd file and search for the given name in the list. This challenge will help us understand how to work with configuration files and how to search for a specific string in a file using shell scripting.
