How to search folder with only x set (execution) permission

Question

I have read that if folder has only x set permission to execute it actually means that you are permitted to search this directory. So how to search it?

Answer 1

You misunderstand. “Search” permission is a bit of a misnomer; if you have execution permission but not read permission on a directory, you can access a file in this directory only if you know its name. That is, given a name, you can search the file with this name (and, more importantly, you can access the file that you find). You do that in the usual way, by accessing the file directoryname/filename. You can't browse the list of entries in the directory, so you can't make more advanced searches such as pattern matching. That would require the read permission; the read permission is precisely what lets you browse the list of entries in the directory.
