IT4575 builds practical competency with the Linux operating system, the foundation underlying most servers, cloud infrastructure, and networking equipment in production environments. Students use command line tools, manage files and processes, configure hardware, and progress into advanced topics including system administration, scripting, and network security and configuration within Linux.
Core Linux administration skill areas
| Skill Area | What It Covers | Common Tools |
|---|---|---|
| File Management | Navigating, organizing, and manipulating the Linux filesystem | ls, cd, cp, mv, chmod, chown |
| Process Management | Monitoring and controlling running programs and system resources | ps, top, kill, systemctl |
| Package Management | Installing, updating, and removing software packages | apt, yum, dnf depending on distribution |
| Scripting and Automation | Automating repetitive administrative tasks | Bash shell scripting |
What IT4575 covers
The course begins with fundamental Linux concepts: the filesystem hierarchy, command line navigation, and basic file editing using command line text editors. Students build comfort with the command line interface as the primary tool for interacting with Linux systems, a significant shift for students accustomed primarily to graphical interfaces. This foundation includes hardware configuration and process management, learning to monitor system resources and control running programs directly from the command line.
IT4575 then advances into administrative topics: managing user accounts and permissions, configuring system services, and using package managers to maintain software. Students apply advanced topics specific to Linux, including writing shell scripts that automate administrative tasks, a skill that scales an administrator's effectiveness across many systems simultaneously. The course closes with network configuration and security within Linux environments, covering firewall configuration and secure remote access, skills directly applicable to managing Linux servers in production settings.

Frequently asked questions
No. Capella does not allow students who received credit for IT4561 and IT4571 to also take IT4575, since these courses cover overlapping Linux content under different course numbering used in earlier catalog versions. If you completed either course, that credit satisfies the IT4575 requirement.
No prior Linux experience is required, though the course requires completion of or concurrent registration in IT3280, IT2180, or IT3318, ensuring some foundational IT systems background. IT4575 is designed to build Linux competency from fundamental command line skills through to advanced administration and scripting, so it accommodates students new to Linux specifically.
Common assignments include a command line skills demonstration covering file and process management, a shell script that automates a specific administrative task, and a network security configuration project covering firewall rules and secure access setup on a Linux system. Capella expects both functional command execution and written explanation of administrative decisions.
While Windows dominates desktop environments, Linux powers the overwhelming majority of web servers, cloud infrastructure, and networking equipment in production use. Most cloud platforms, including AWS and Azure, run Linux-based virtual machines at massive scale, and many DevOps, cybersecurity, and systems administration roles require solid Linux command line competency as a baseline expectation, regardless of what operating system end users interact with.
