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)

You don't typically have permissions "become defective" or need them to be "repaired" in a Linux system. Nearly all system files, with their permissions, are included in packages. Everything else should be considered user data.

If you logged in as root and did something dumb, you could attempt to fix the permissions by reinstating packages.
