There needs to be a Linux kernel fork that when you try to execute a directory executes all programs in the directory. In parallel. Juuuuuuuust to fuck with people who might accidentally execute the /usr/bin directory.
Those of us who use the autocd feature of shells “execute” directories all the time. For example I’d type just /usr/bin RET if I wanted to cd to /usr/bin.
For directories, it’s permission to cd into it. Read is whether you can list files, and write is remove, rename, or create new files. Don’t ask questions about the secret sticky bit
The x permission on directories is exactly for this purpose. You can use the directory. You cannot read (requires rx), you cannot write (w), but you can ‘cd’ and operate on files in the directory.
This is important, you can lock someone out from a directory tree buy not giving them ‘x’ on the root. So, if your home is rwx------, no one but the owner can do anything in your home. This is effective even if some files and subdirectories have less restrictive permissions.
I remember myself asking why directories had x flags in their permissions. Like, you don’t execute them. What do they use the x flag for?

Or worse… In order. Based on last Modified date. And use that as the basis for some scheduling agent where timing and order of execution is essential.
That’s the most evil thing I’ve heard in awhile, and I would absolutely make use of it anyway.
All you have to do is touch the files in order. Why aren’t you using this touchsched repo here….

Does that include root?
Point for you, root is special.
Executing a list read of the inode?
