File System Stepbystep 1 Open your terminal 2 Use the pwd command to check your current directory 3 Use the ls command with various options eg ls l ls a to list files and directories 2 4 Navigate through the file system using cd eg cd homeuser 5 Create a new directory using mkdir Best Practice Familiarize yourself with the Linux file system hierarchy This knowledge is crucial Pitfall Incorrect use of path separators 2 User and Group Management Stepbystep 1 Create a new user using the useradd command eg useradd newuser 2 Set a password using the passwd command eg passwd newuser 3 Modify user attributes using usermod 4 Work with groups using groupadd and groupmod 5 Understanding the chown and chmod commands for file permissions Best Practice Use descriptive usernames and group names Pitfall Forgetting to set a password for the new user 3 Package Management with apt Stepbystep 1 Open your terminal 2 Update the package list using sudo apt update 3 Install a package using sudo apt install packagename 4 List installed packages with apt list 5 Upgrade installed packages with sudo apt upgrade Best Practice Use sudo when performing administrative tasks Pitfall Typing incorrect package names 4 System Services Stepbystep 1 Use systemctl to manage services 2 Check service status with systemctl status servicename 3 Start stop and restart services with systemctl startstoprestart servicename Best Practice Learn about initd scripts and the various service management tools Pitfall Not understanding the implications of stopping crucial services 5 Networking 3 Stepbystep 1 Use ifconfig or ip addr show to view network interfaces and configurations 2 Use ping to test network connectivity 3 Use traceroute to track network paths Best Practice Understand network configurations such as IP addresses DNS servers and gateways Pitfall Mistaking one network interface for another Common Exam Strategies Focus on practical application Apply your knowledge in lab environments Master
