39,199 PointsExecute permission on a directory is sometimes called search permission. If you found a directory that gave you execute permission, but not read permission, you could use any file in that directory. However, you must know the name. You cannot look inside the directory to find out the names of the files. Think of this type of directory as a black box. You can throw filenames at this directory, and sometimes you find a file, sometimes you don't.

I guess you/they are referring to --x combination for directory mode as a "black box". Interesting stuff, must think over all combinations. Also, I wanted to ask about that i-node number, and there are special bits I never dived in deep enough. Perhaps now is the time for me to clear all this up ... excellent tutorial.

I think you've got that backward.
If there was a file in a directory with the permissionsr-- you would be able access the file only if you knew the name, because you lacked the permission to list the files in the directory.

4,248 PointsMaybe I am backward :). If dir1 has d--x------ permissions, and dir1/file1.txt has -rw------- and same user/group, that user can't list dir1 but can edit/save file1.txt. So I put --x referring to this and black box.
