-h human readable
Lists the size in human readable form and lists the top 25 biggest directories/files
Also shows files as they are found. Only works from a tty.
In OSX you would have to make sure that you "sudo -s" your way to happiness since it will give a few "Permission denied" errors before finally spitting out the results. In OSX the directory structure has to start with the "Users" Directory then it will recursively perform the operation.
Your Lord and master,
the -h option of du and sort (on appropriate distrib) makes output "Human" readable and still sorted by "reversed size" (sort -rh)
This command give a human readable result without messing up the sorting.
