Space left under current directory

What utility (or combination of utilities) can I use to find out how much disk space a directory and its subdirectories take up.

I currently am using 'df' to see partition space/size,
'ls' doesn't seem like displaying directory info

TIA

I use <B>du</B> and summary flags like du -sk or du -sb.

as neo said du is the utility you want.

this script goes to each filesystem and lists the first level directorys in that filesystem by size in kb. use it if you like alter if you wish but its here.

#! /bin/ksh
#
# This will take a look at all Filesystems NOT left out in the variable FILESYSTEM and
# then find all directoy sizes listed in that filesystem and print them to standard output
# in a formated output. All sizes are in kb.

FILESYSTEM=`df -n|grep -v proc|grep -v dev/|awk '{ print $1 }'`

for FS in ${FILESYSTEM};do
        FREE=`df -k|grep $FS|awk '{ print $4 }'`
        USED=`df -k|grep $FS|awk '{ print $3 }'`
        cd $FS
        echo "-=Disk Spaceing Script (all sizes are in kb)=-"
        echo '\t' by: dooley.michael@con-way.com
        echo DISK ${FS}
        echo
        echo TOTAL AVAILABLE $FREE
        echo
        echo USED:
        echo '\t' $FS
        for DIRECTORY in `ls ${FS}`; do
                if [[ -d $DIRECTORY ]]; then
                        du -s $DIRECTORY|awk '{ printf ("%25s\t%-10d\n", $2,$1) }'
                fi
        done
        echo TOTAL USED ${FS}"\t"$USED
        echo
done
