Switch scripting .sscript inflating pre-commit hook

pre-commit

#!/bin/sh

# Create a file with these contents in your repo at
# .git/hooks/pre-commit

# Place any .sscript files in a folder called Packed/

# Extract any .sscript files from a Packed/ directory
for i in `find . -name "*.sscript" -type f -exec echo \{\} \;`; do
		# Only act if within a Packed directory
		act='No';
		case "$i" in
			*/Packed/*) act='Yes' ;
		esac

	# Unpack
	if [ $act = 'Yes' ];
		then
			# Say something
			echo "Found ${i}"
			# Get the unpacked destination
			unpacked_temp_destination="${i/Packed/Unpacked}"
			unpacked_final_destination="${unpacked_temp_destination%.sscript}"
			# Unzip
			echo "Making '$unpacked_final_destination'"
			unzip -o -q "$i" -d "$unpacked_final_destination"
		fi
done

this stopped working with Switch 13 update 1, now the unpacked scripts are all gibberish
