A long time ago I ran into a simple program called treesize which allows you to run it in any directory and will give you a listing of the directories with the amount of KB/MB/GB is used in that directory.
run : vi /usr/bin/treesize
and paste this content:
du -k --max-depth=1 | sort -nr | awk '
BEGIN {
split("KB,MB,GB,TB", Units, ",");
}
{
u = 1;
while ($1 >= 1024) {
$1 = $1 / 1024;
u += 1
}
$1 = sprintf("%.1f %s", $1, Units[u]);
print $0;
}
'
Close vi and execute: chmod +x /usr/bin/treesize
