Or you could just grep the directory, not saying you have to do this, but
this was kind of fun to write anyways, if i spent more time on it, i could
perfect it, but i dont have that kind of time, so this will still give you a
few doubles, but it shouldn't give you false-positives as long as you have
all the extensions in that grep regex (and you cant make it more generic
without introducing false-positives)...

grep -oiPR "[a-zA-Z0-9]+\.(php|js|png|
jpg|css|htm|html)" directory | awk 'function getfiles(input, files, i, n,
file) {result = ""; n=split(input, files, ":"); for(i=0; i<=n; i++) {
if(files[i] !~ /^\s*$/) print files[i];}} {getfiles($0)}' | sort -biu

This should give you all the files that reference files and the files they
