1 Basic Navigation

Navigating through the file system is a fundamental skill when working with Linux. The pwd command stands for "print working directory" and shows the current directory you're in. To list the contents of a directory, use ls , and to change directories, the cd command is your friend. Remember, Linux is case-sensitive and paths usually start from the root directory, denoted by "/". Mastering these commands will provide a solid foundation for your journey in Linux.

2 File Management

File management is a critical aspect of Linux. Beginners should familiarize themselves with commands like touch to create empty files, cp for copying files, mv to move or rename files, and rm to delete files. Understanding directory management with mkdir to create and rmdir to remove directories is equally important. These commands help in organizing and maintaining the file structure, which is crucial for efficient business operations.

3 File Editing

Editing files is a frequent task in Linux. The nano , vi , and vim commands open text editors that allow you to modify files directly in the terminal. Nano is often considered the most beginner-friendly, but learning vi or vim can be beneficial as they are more powerful and available by default on most Linux systems. Knowing how to edit files is essential for tasks like configuring system settings or writing simple scripts.

4 System Information

To effectively manage Linux systems, you need to know how to retrieve system information. The uname command displays basic system information. Use df to report file system disk space usage and du to estimate file space usage. The top command provides a dynamic, real-time view of running processes, crucial for monitoring system performance. These commands help you understand the state of your system, ensuring smooth operations.

5 Permissions Control

Linux's permission system controls who can access files and directories. The chmod command changes the permissions of a file or directory, while chown changes the owner. Understanding permission settings, represented by three sets of characters for the owner, group, and others, is vital for securing your system and preventing unauthorized access—a must-know for maintaining operational integrity.

System administration commands need to be considered if there is more than one person using that computer. Between distributions, they may have different names or strategies to do so as well. Consider GNU coreutils which cover pretty much every command in a GNU system. Su, Sudo if installed, passwd, shadow, chage, id, the various commands for users and group management, whoami, w, ssh are some commands to start out with.

Networking is an integral part of business operations, and Linux offers powerful networking commands. ping checks the connectivity to another server or device. Use ifconfig or ip addr to display network interfaces and configure IP addresses. For viewing routing tables and network interfaces, the netstat command is quite useful. These commands allow you to troubleshoot network issues and ensure your business stays connected.
