BASH case insensitive path checking. (effificently)

I needed to check some paths for files. I have a script that calls a copy function on some files that were previously mounted on a case insensitve system. I couldn't find anything, so instead of using `find -i` which would be a resource hog i wrote this: -

#!/bin/bash
old_IFS=$IFS
if ! [ -a $1 ]; then
	trypath=""
	path=""
	IFS=$'/'
	for i in $1; do
		trypath=$path$i"/"
		if [[ -a $trypath ]]; then
			path=$trypath
		else
			ipath=`ls "$path" | grep -i $i`
			path=$path$ipath"/"
		fi
	done
	echo "$path"
else
	echo "exists"
fi
IFS=$old_IFS
