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 also do
chmod +xto add the executable bit to whatever the existing perms are.0: no permissions
+4: read
+2: write
+1: execute
I often go
chmod -R go+rX .if I want to give read-only access to whatever I'm working on to everyone else. The capitalXonly sets the executable bit on directories.
