Sort by size, then list file in each directory
Hi,

I have directories with name like:
aaa
bbb
ccc
...

I would like to to see which directories are the largest and then list the files within each. I have success using:

Code:
du -ks * | sort -rin | head -n 20

which gives me an output like:
120 bbb
27 ccc
3 aaa
...

I would like to be able to do a simple "ls" so I have a clearer view of what's in each of the big directory. Without knowing anything about xargs, I am trying:

Code:
du -ks * | sort -rin | head -n 20 | xargs ls

which gives me (on top of the errors) an alphabetical order list of "ls", instead of what I would like which is more like a "-exec ls {}" in "find"...

ls: 3: No such file or directory
ls: 120: No such file or directory
ls: 27: No such file or directory
aaa:
will_cover_page.gif

bbb:
will_dependents_page_2.gif will_dependents_page_4.gif
will_dependents_page_3.gif

ccc:
will_dependents_page_1.gif will_signatures.gif

Is there a more efficient way of doing this? Thanks in advance...

fatsort

fatsort(1)						      General Commands Manual							fatsort(1)

NAME

       FATSort - FAT filesystem sorting utility

SYNOPSIS

       fatsort [options] device

DESCRIPTION

       FATsort sorts directory structures of FAT filesystems.  Many MP3 hardware players don't sort files automatically but play them in the order
       they were transmitted to the device. FATSort can help here.

OPTIONS

       -c     This option causes FATSort to ignore the case of filenames (e.g. 'example.mp3' is equal to 'EXAMPLE.MP3').

       -f     Force sorting even if the device is mounted or if FATSort cannot determine if the device is mounted.

       -h     Shows some help information.

       -i     Prints some file system information of the specified device.

       -l     FATSort will not sort directory structures, but just print the current order.

       -o type
	      This options specifies how FATSort will sort files and directories.  type can be 'd' for directories  before  files  (which  is  the
	      default), 'f' for files before directories, or 'a' for no differentiation between files and directories.

       -n     Uses natural order to sort directory structures instead of  alphanumeric order.  For example, an alphanumeric order would be
		     file123.mp3
		     file21.mp3
		     file3.mp3
	      and the corresponding natural order would be
		     file3.mp3
		     file21.mp3
		     file123.mp3.

       -q     FATSort will work quietly without printing additional information messages.

       -r     Sorts the directories in reverse order (Z-A).

       -R     Sorts the directories in random order.

       -v     Shows version information only.

       The following options can be specified multiple times:

       -d directory
	      Sort directory only

       -D directory
	      Sort directory and all subdirectories

       -x directory
	      Don't sort directory

       -X directory
	      Don't sort directory and all subdirectories

       -I prefix
	      Ignore  filename	prefix	prefix	during sorting. For example, passing option -I "the " tells FATSort to sort 'The Beatles.mp3' like
	      'Beatles.mp3'.

EXAMPLES

       Sort FAT filesystem on an USB stick:
	      fatsort /dev/sda1

       Sort FAT filesystem in a file:
	      fatsort /home/user/fat16_fs.img

       Sort directory /dir1 and all subdirectories except /dir1/dirA:
	      fatsort /dev/sda1 -D /dir1 -x /dir1/dirA

       Ignore prefixes 'a ' and 'the ' during sorting:
	      fatsort /dev/sda1 -I "a " -I "the "
