Finding only names in a dir and searching for case issues

perl_mystery has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks, I need a starting point to achieve the following tasks.Can any one pls give me a sample code to start with?

1.Get all the folder and file names recursively in a directory 2.search recursively for the names obtained in step#1 in a directory and report those filenames (of the searched name or folder in step#1) which has case-sensitivity issues

Algorithm: Use File::Find (Core) or File::Find::Rule (CPAN) to create a list of files. For each file, get the basename of the file. Store the lc of the basename as a key in a hash, the value being the full file name. If a hash key already exists, print out both full file paths.	[reply]

I am not sure how this helps,for example,lets say there a file name "Data.h" in our list of files,and there is a file "foo.c" which has #include "data.h"(observe the case-sensitivty for letter "d").Now I want to print the file name and the #include line.Can anyone give a sample code or atlease suggest a correct algorithm?

Sounds like you're looking for functionality like this: `ls -1 \| while read filename; do grep -ir "$filename" * \| grep -v "$fil +ename" ; done` [download] (However, this is not perl :)	[reply] [d/l]

Thanks for the response.I did check-out that but I am not entirely sure how to use it to catch the case-sensitivity thing. I know I can use file::find to get the files and directory names,how to take care of step#2?	[reply]
