Analyzing Linux Disk Space with df and du

Running out of disk space on a critical Linux server can cause application failures, database corruption, and system crashes. Knowing how to quickly inspect your storage and pinpoint exactly what is consuming your disk space is an essential skill for any system administrator, developer, or DevOps engineer. This course teaches you how to confidently navigate the Linux filesystem to monitor and manage storage resources. You will transition from guessing why a disk is full to systematically identifying storage bottlenecks and resolving them before they impact your applications. What you'll learn: - Understand the core differences between the df and du commands and when to use each - Analyze filesystem capacity and available space in human-readable formats - Locate large files and directories consuming excessive disk space using command flags - Interpret storage metrics, mount points, and virtual filesystems accurately - Identify hidden disk space consumers such as unlinked open files and inode exhaustion - Combine disk utility commands with filters like grep and sort for efficient troubleshooting This course begins with foundational concepts of Linux storage, partitions, and filesystems before moving into practical command-line operations. You will read clear explanations, study real-world output examples, and practice with written troubleshooting scenarios. This course is designed for beginners who are new to Linux administration or developers who want to manage their own cloud servers. No prior system administration experience is required.
