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.

No one mentioned ACLs so far. If you see a + using ls -l like this
drwxrwx---+, you have an access control list entry.access control lists
More than a decade of using linux and I still can't remember
setfaclsyntax. I have better luck rememberingtarsyntax.tar -xzfextract ze fileAnd
tar -czfcompress ze file. I saw someone post these mnemonic devices a while back and now I actually remember tar commands. Amazing!This is a very useful way to remember it, but nowadays it's better to drop the z (which immediately makes the mnemonic more forgettable, of course). tar can autodetect compression now, so
tar -xfshould work on anything from plain tar archives over tar.gz to more unusual compression algorithms like tar.xz or tar.bz2.(the z is specifically for gzip)
You don't even need the dash (
-).and then what is the thing that will happen to us next
