Monitoring hard disk space is essential for the smooth functioning of any Linux system. Several commands can be used to check hard disk space usage, each with its advantages and use cases.
The ‘df’ command is a versatile tool that displays the amount of disk space used and available on all mounted file systems. It provides a comprehensive overview of disk usage and can be used with various options to customize the output. For example, the ‘-h’ option makes the output more readable by displaying file sizes in human-readable format.
