I have the following script:

#!/usr/bin/ksh

export MDIR=/datafiles

NAME=$1
SERVER=$2
DIRECTORY=$3
DATABASE=$4
ID=$5

export dirlist=`/usr/bin/ssh -q $ID@$SERVER find $DIRECTORY -type d -print`
for dir in $dirlist
do
SIZE=`</dev/null /usr/bin/ssh -q $ID@$SERVER du -ks $dir`
echo $NAME $DATABASE $SIZE $DIRECTORY>> $MDIR/bldtuout.txt
done


It is running forever, but does return the correct results. Is there a faster way? My goal is to have the directory sizes of all directories under a given path.
