A shell script that checks files for entropy then orders files by highest entropy and saves the paths to a file called `entropy.txt`

entropy.sh

echo "Getting entropy readings from all .php files"
rm -rf entropy.txt entropy.tmp.txt
for entry in $(find . -type f -name "*.php" -maxdepth 4); do
    entropy=$(ent $entry | sed -n 's/.*Serial correlation coefficient is //p' | sed "s/ .*//")
    echo "$entry $entropy" >> entropy.tmp.txt
done
sort -k2 -n entropy.tmp.txt > entropy.txt
rm -rf entropy.tmp.txt
echo "Entropy readings saved to entropy.txt"
