Shell Script Retokenize Property Values to Keys For All Files In a Directory - bash

Question

Previously, I wrote a small shell script to "retokenize" a file (useful for comparing for sanity checks). I'm currently in the need of doing something similar for a folder instead of just one file.
I'm curious if there is an easy way to rework the following to be like a method / function and how to recursively pass all files in a folder to the method, so that the end result is that all files in the folder are "retokenized". Hoping to see if there is a quick and easy way to do this. Being doing some googling and playing around, but want to see if anyone here has a quick / easy / clean solution.
Working version for one file:
#!/bin/bash
date
outputDump="output.txt"
prodPropsFile="input.properties"
prodPropsSortedFile="sorted.properties"
tempPropsFile="temp.properties"
echo "Removing comments and empty lines from prod properties file"
sed '/^#/d' < $prodPropsFile > $tempPropsFile
sed '/^s*$/d' < $tempPropsFile > $prodPropsSortedFile
cp $prodPropsSortedFile $tempPropsFile
echo "Sorting prod properties by value length. So don't do double tokenization"
awk -F"=" '{ st = index($0,"="); print length(substr($0,st+1)),$0 }' $tempPropsFile | sort -rn | cut -d" " -f2- > $prodPropsSortedFile
echo "Retokenizing."
while IFS== read k v;
do
# Sed escape /, \, and &. Needed for urls like jdbc connections, etc.
escapedV=$(echo $v | sed -e 's/\\/\\\\/g; s/\//\\\//g; s/&/\\\&/g')
# The /gI will replace the tokens globally with case insensitive, this is important in case someone does something like "http://..." versus "HTTP://...".
sed -i -- "s/$escapedV/$k/gI" $outputDump;
done < "$prodPropsSortedFile"
Example property file:
%%token1%%=value1
%%token2%%=value2
Example input file:
This is a file that has value1 and value2.
Example output file:
This is a file that has %%token1%% and %%token2%%.

Updated Script that Works for All Files in a Folder on my Mac:
#!/bin/bash
date
retokenize()
{
echo "Retokenizing $file"
while IFS== read k v;
do
# Sed escape /, \, and &. Needed for urls like jdbc connections, etc.
escapedV=$(echo $v | sed -e 's/\\/\\\\/g; s/\//\\\//g; s/&/\\\&/g')
sed -i '' "s/$escapedV/$k/g" $file;
done < "$prodPropsSortedFile"
}
# Copy our input to a output file that we will modify, so we don't affect the original.
inputDump="IIQExports"
prodPropsFile="input.properties"
prodPropsSortedFile="sorted.properties"
tempPropsFile="temp.properties"
echo "Removing comments and empty lines from prod properties file"
sed '/^#/d' < $prodPropsFile > $tempPropsFile
sed '/^s*$/d' < $tempPropsFile > $prodPropsSortedFile
cp $prodPropsSortedFile $tempPropsFile
echo "Sorting prod properties by length."
awk -F"=" '{ st = index($0,"="); print length(substr($0,st+1)),$0 }' $tempPropsFile | sort -rn | cut -d" " -f2- > $prodPropsSortedFile
echo "Retokenizing."
find ./$inputDump/ -type f > foo.txt
IFS=$'\n';for file in $(cat foo.txt);
do
retokenize $file;
done
echo "Done."
