I'm looking for a script that will find the 20 largest files in the root filesystem, but will ignore mounted filesystems. I need to do some root cleanup, but I can't see the largest files.

A standard du should work. It could get more advanced, but you're just asking for problems. -k for kilobytes. -x for not hopping filesystems. and sort the output numerically.
# du -kx / | sort -n

I use this for my users, it works pretty good

$ shrimp /usr/users/alexisl> cat get_du
# This is get_du
cd /usr/users
oper=/usr/users/operator
larry=/usr/users/alexisl
ls > $larry/dir_list
num_dir=`wc -l $larry/dir_list|cut -c 5-8`
echo $num_dir
$larry/du_report < $larry/dir_list

$ shrimp /usr/users/alexisl> cat du_report
# This is du_report, it report on disk use in the /usr directory
cd /usr/users
oper=/usr/users/operator
larry=/usr/users/alexisl
rm $larry/full_du.txt
num_dir=`wc -l $larry/dir_list|cut -c 5-8`
echo $num_dir
read dir_name
set `date`
today="$1 $2 $3 $4"
echo "\t The top offenders as of $today \n" > $larry/top_offenders.txt
echo " MB \t Directory/file " >> $larry/top_offenders.txt
echo "\t This is the Disk Usage Report for the /usr/users directory as of $today" > $larry/disk_usag
e.txt
echo "_________________________________________________ ___________________________" >> $larry/disk_u
sage.txt
echo " " >> $larry/disk_usage.txt
let x=1
while [ $x -le $num_dir ]
do
echo "List of files and sizes for $dir_name" >> $larry/disk_usage.txt
echo "MB \t Filename " >> $larry/disk_usage.txt
echo "______________________________________" >> $larry/disk_usage.txt
du -am $dir_name >> $larry/disk_usage.txt
wait
du -am $dir_name >> $larry/full_du.txt
echo " " >> $larry/disk_usage.txt
x=$x+1
read dir_name
done
sort -n $larry/full_du.txt > $larry/full_du.sort
tail -20 $larry/full_du.sort >> $larry/top_offenders.txt
cat $larry/top_offenders.txt

Hi There

find . -type f -xdev | xargs ls -ld | sort -rnk 5 | head -20

the -xdev will ensure the command does not traverse filesystems

If you want a list from / of all files on the server

find . -type f -ls | sort -rnk 7 | head -20

HTH
