Monitoring disk usage is a critical aspect of system administration in Unix-like operating systems. Knowing how to check disk usage allows system administrators to proactively manage storage space, identify potential issues, and ensure optimal system performance.
There are several commands available in Unix to check disk usage. One of the most commonly used commands is “df”. The “df” command provides a summary of disk usage for all mounted file systems. It displays information such as the file system’s total size, used space, available space, and mount point.
