creating a recursive DIFF command
I need to find the difference between 2 directories, basically I need to know what exists in the first directory that doesn't exist in the second directory. They are set up like the following:
/files/ ---(FIRST DIRECTORY)
file1 file2 file3 file4
The directory 'Files' has subdirectories which are supposed to contain all of the files in the directory 'files'. I need to find out if all of the files in /files/ are in /Files. I tried the command diff -r /files/ /Files/, but it was telling me that some of the files were only in 'files' when i know they existed in both.
Is there a better way to do this?
