I want to have a place on the filesystem that presents a write-only "view" of another folder that I have read-write access to.
I'm picturing something that's similar in behavior to an FTP drop box, where files can be copied into it but not read out of it, e.g.:
$ ls read-write-view/ write-only-view/ read-write-view/: a b c write-only-view/: $ cp d write-only-view/ $ ls read-write-view/ write-only-view/ read-write-view/: a b c d write-only-view/:
It's important that this works as in the example — the contents are still visible when accessed through
read-write-view/, and both "views" are functional for a single user.
How can I set something like this up? Some clever arrangement of symbolic links, perhaps? Or an unusual configuration of a bind mount?
