How do I batch change files' UNIX settings? I have web sharing turned on and have it set up so it's serve up the files and folders on my hard disk. It works great, but when I look at the folders it's showing in the web page, approximately 1 in 10 folders just isn't being displayed. The OS X permissions on these folders is all set to "read and write" for everyone, so I presume there is some sort of other UNIX or Apache file/folder settings that are keeping these folders from being displayed in the webpage. How do I make these hidden folders show up in my web page's displayed directory of folders?
