Df
Df is a command-line utility in Unix-like operating systems that reports the amount of disk space used and available on mounted filesystems. It displays information such as total space, used space, available space, and usage percentage for each filesystem, helping users monitor disk usage and manage storage efficiently.
Also known as: df command, disk free, df -h, df -k, disk usage report
🧊Why learn Df?
Developers should learn Df to troubleshoot disk space issues, optimize storage allocation, and automate system monitoring in server environments. It is essential for tasks like checking if a server has enough free space for deployments, logs, or databases, and is commonly used in shell scripts for system administration and DevOps workflows.
