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.

The “-“ is often not necessary. I use it as a guide to see how long the person running tar has been using it.
Example:
tar -xf file.tar == tar xf file.tar
They are functionally flags though and uniletter flags should be preceded by a '-', so I would still prefer to have the '-' written, because it conforms with the standard.
But muh POSIX
yeah, you can also ditch that f
tar c /etc/passwd > fu.tar
tar t < fu.tar
tar x < fu.tar
