# What is the best (fastest) method of finding large files that will cause a directory (i.e. /usr) to go to 100%. I check for core dumps and log files immediately but there has to be a better way to find huge files quickly.
# 3Thanks for any assistance.

#!/bin/sh

if [ $# -eq 2 ]
then
find $1 -type f -xdev -size +$(expr "$2" \* 2) -exec ll -d {} \;
else
echo "Usage : ${0##*/} "
fi

Run it this way:

./bigfiles.sh /var 5000
