Running out of disk space on your Linux server and need to find the files taking up the most space? The du or Disk Utility command is a standard Linux command, used to check the information of disk usage of files and directories. Below is the command that will list out the files and folders in the current directory in descending order.
Sort DESC in human-readable format
du -h | sort -h -r
