I just noticed that after running
chmod 777 *
on a directory that has sub-directories in it does what you would expect. It sets the permissions of everything, including the sub-directories to 777. However, if you then decided that you didn't want to do that, and run
chmod 644 *
Now the contents of the sub-directories get set unknown permissions and you cannot change them back.
Why does that happen? Is this the expected behavior, or a bug? Is there a way to restore the file permissions?
Since the files I had were in a zip file in another location, I just deleted the entire directory, and unzipped the zip file again, but I would like to know the causes of this "problem", and it's remedies.
Some additional info, I am running those command on a remote machine over SSH.
