My note was related to the below example.
example_dir_for_iteration contains say 5 entries as follows (dira,
text_file_a,socket_file_a,block_device_file_a,zip_file_a), in else block of the
code, we are copying all files. Now, in your case where you explicitly
mentioned key file path(/root/..) these file types may not be possible, but
these type of copying without file types checks, leads to vulnerabilities in
the application long run. So, i mentioned to see we are copying files as
mentioned in else block, do we want to add some file type check that we are
interesting in copying, for that i gave an example where directory contains
multiple file types.
