The du command, standing for "disk usage", can be employed to ascertain the size of files and directories. du -sh filename would display the size of a file, while du -sh directory_name reveals the total size of a directory. The -s provides a summary and -h displays sizes in a human-readable format (like KB, MB). It's an invaluable command for monitoring space utilisation and managing storage effectively.
