Jayjan jay!! Don't use find with exec unless you have to do stuff inside the exec!

Replace with :
Code:
find $DIR -printf "%k\n" | awk '{sum+=$1}END{print sum}'

Here's what you can do: find all the dirs in depth-first order, then feed each dir into du.
Code:
find $DIR -type d -print | 
  awk 'BEGIN{OFS="\t"}{ print $0,split($0,x,"/"); }'  |
  sort  -k 2nr,2 -k 1,1  | 
  cut -f1 |
  xargs -L 1  -t du -sh 2>&1 |
  $PAGER

Here's what we're doing: The find gets all the directories (your target dir is $DIR) and prints them out one line at a time. The awk command then prints out each directory name followed by its depth -- determined by the number of times split found the / character in the input line. We separate the fields by tabs to prevent long and unusual dir names from getting clobbered by the next steps. Next, sort orders the list by directory depth. Now that the list is ordered, we dont need the depth information anymore, so the cut command strips it (you can also do this with awk or sed). Finally, the resulting list is fed into xargs, which prints out and executes the command "du -sh" on each directory, one directory at a time.

The output is then sent through your $PAGER, which ought to be defined. If not, use "less" or "more" whichever works for you.

This way, you can find a particularly large directory without waiting forever for the job to finish.

fs_quota

FS_QUOTA(1)						       AFS Command Reference						       FS_QUOTA(1)

NAME

       fs_quota - Displays the quota used in the volume containing a directory or file

SYNOPSIS

       fs quota [-path <dir/file path>+] [-help]

       fs q [-p <dir/file path>+] [-h]

DESCRIPTION

       The fs quota command displays the percent of quota consumed in the volume that contains each specified directory or file.

       To display more detailed information about the volume and the partition it resides on, use the fs examine and fs listquota commands.

       To set volume quota, use the fs setquota or fs setvol command.

CAUTIONS

       Currently, the maximum size of a volume is 2 terabytes (2^31 bytes).

OPTIONS

       -path <dir/file path>
	   Names each file or directory for which to display the quota consumed in its parent volume. Partial pathnames are interpreted relative
	   to the current working directory, which is also the default value if this argument is omitted.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output reports the percent of volume quota used, in the following format:

	  <percent>% of quota used.

EXAMPLES

       The following command lists the percent quota used of the volume housing the current working directory:

	  % fs quota
	  17% of quota used.

       The following command lists the percent quota used of both the volume housing the current working directory's parent directory and the
       volume housing the directory /afs/abc.com/usr/smith:

	  % fs quota -path .. /afs/abc.com/usr/smith
	  43% of quota used.
	  92% of quota used.

PRIVILEGE REQUIRED

       The issuer must have the "r" (read) permission on the ACL of the root directory of the volume that houses the file or directory named by
       the -path argument, and "l" (list) permission on the ACL of each directory that precedes it in the pathname.
