Check Used Space on a Disk/ Mount Point
———————
The du command summarizes your disk usage. The sort command sorts the files by size. The command shown below sorts from smallest to largest all files in the current directory and all directories contained below the starting directory. Because the sort starts with the smallest file, the end of the list shows the largest files.
Deleting a large file is usually more efficient than deleting many small files. Often the largest files are core files or cache files, both of which you can delete.
du -h –max-depth=1
du -a | sort -k 1n,1|tail -30
du -sk * | sort -n | tail
Files more than 5mb
