This article provides a learning path through an introduction to Linux concepts. Use the sections in the article as a guided learning path to familiarize yourself with the Linux environment.
This list isn't comprehensive but instead provides the bare minimum you need to help you administer and navigate your SQL Server on Linux environment. See the full list of tutorials to learn more.
What is Linux?
The What is Linux module introduces the history of Linux as an operating system. The module explains the Kernel and where Linux is today. This tutorial serves as an introduction to Linux, helping you get started.
Select a distribution
After you know the history of Linux, decide which distribution of Linux best suits your business needs.

SQL Server 2022 (16.x) and earlier versions are also supported on SUSE Linux Enterprise Server (SLES).
Get around directories
After you choose the appropriate distribution of Linux, familiarize yourself with getting around Linux directories.
This module helps you answer the following questions:
- How to navigate between different files
- How to identify a file from a directory
- Identify different directories
Install new software
Next, learn how to install new software on your new Linux operating system. This module covers installing new software on the Debian and Red Hat Linux operating systems.
Root versus system user
Understand user permissions, and the difference between a root user and a system user. This module helps you decide which user permissions are appropriate for each scenario.
File system and permissions
After you're familiar with recognizing different users and groups in Linux, learn how you can change ownership and file permissions on different files in Linux operating systems using the chown (change ownership) and chmod (change permissions) commands.
