Linux administration starts at the command line — and this course builds the skills you need to work there with confidence.

You'll begin by setting up your learning environment and understanding how the LFCS certification is structured. From there, you'll learn to access Linux systems locally and remotely, navigate the filesystem, use system documentation, and manage files, directories, and symbolic links from the CLI. The course then covers file permissions in depth: reading and modifying standard permission bits, understanding when to apply SUID, SGID, and the sticky bit, and locating files efficiently by name, type, and attributes. These are skills you'll use in every future administration task. In the final module, you'll build text processing and version control skills: searching file content with grep, writing basic and extended regular expressions, comparing and manipulating files, compressing and archiving data, and managing I/O redirection. You'll also work with SSL certificate files and perform core Git operations — committing changes, managing branches, and working with remote repositories. Every topic is reinforced with hands-on labs that build the command-line precision required for the LFCS exam and real-world administration work. Who this is for: Aspiring IT professionals, junior system administrators, and developers with no prior Linux experience who want to build a strong CLI foundation aligned with the LFCS exam objectives.
