From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You can't cd or ls in a folder if you have no +x permissions on it. That is all. I wasted 3 hours of my life. (szmer.info)

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.

Does that include root?

Point for you, root is special.
