bash - How to grep for new folders which don't match folders from the pattern -

i need following in bash:

go folder , recursively check new files in current folder, new files last update time >=d - 7 days, remember name of every new files

i this: find ./ -type f -ctime -7 -exec ls {} \; > new.files

then need go previous directory cd ../ , find new folders created not white list (the list of folders) , updated during last 7 days. if find directory need go directory , check new files did before (find ./ -type f -ctime -7 -exec ls {} \; > new.files.from.new.dir)

as result should send list of new files , list of new directories (not white list) new files.

thank in advance help!

here's finished, refined script! note cool use of redirection. :)

...sorry version posted earlier non-working, made super-cool new version, building on basic idea original.
