Copied here as I often find links disappear.

#!/bin/bash

# du of each subdirectory in a directory for ASM

if [[ -z $D ]]
then
 echo "Please provide a directory !"
 exit 1
fi
(for DIR in `asmcmd ls ${D}`
 do
     echo ${DIR} `asmcmd du ${D}/${DIR} | tail -1`
 done) | awk -v D="$D" ' BEGIN {  printf("\n\t\t%40s\n\n", D " subdirectories size")           ;
