What information does the 'df' command provide?

The 'df' command is primarily used in Linux and other Unix-like systems to report the amount of disk space used and available on the mounted filesystems. When you execute this command, it displays information such as the total size of each filesystem, the amount of space used, the amount of space available for use, and the mount point of each filesystem.

For example, running 'df -h' provides this information in a human-readable format, utilizing appropriate size units like kilobytes (K), megabytes (M), and gigabytes (G) to make it easier for users to understand the space utilization. This command is crucial for system administrators to monitor disk space, ensuring that the system does not run out of storage, which can lead to operational issues.

In summary, 'df' serves a specific purpose related to monitoring and managing disk space, making it an essential tool in system management and maintenance tasks.
