Two very simple scripts in my toolbox :

1: 'lsd' : to list only the directories
[lsd= ls + d (directories) ]


ls -p $* | grep /

2: 'lsds' : to list the disk usage of each of those directories
[lsds = lsd + s (summaries) ]


for d in `lsd` # lsd is described above
do
du -s "$d"
done

REM: I use it often as


lsds | sort -n

Thanks for the input. I've added both your shortcuts to my script libraries.
