Checking for "orphan" files
Hello,
I would like to "clean up" a directory AND its sub-directories by deleting ALL scripts and images that are not called
by any other script or webpage within that directory or its sub-directories.
So I want a list of ALL files in my directory (excluding any file that starts with the text 'index') where the file name is not included as text in any other file in that directory or its sub-directories.
How can this be done?
Thanks!

What if there are multiple files by same name in different directories? Do the files contain absolute paths?

Thanks for the good questions. I hadn't throughly thought this through before you asked them.
>>Do the files contain absolute paths?
Not always, sometimes the path is relative, sometimes it is absolute and sometimes
the path name is called from a variable.
>>What if there are multiple files by same name in different directories?
That is a good question and it makes a good point.
To be safe, I will leave ALL files called "image.gif" in ALL subdirectories if ANY script contains the text "image.gif" at least once. In this case, better safe than sorry.

find /top/dir -type f > filename.txt
cat filename.txt | while read filename
do
fname=`echo $filename | sed 's:.*/\(.*\)$:\1:'`
ret=`grep -R "$fname" /top/dir`
if [ -z "$ret" ]
then
echo "File $fname was not found"
else
echo "File $fname was found"
fi
done
Make sure ot works as expected on test data. When you are sure, replace echo command in if then part with rm -f $filename
