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.

There's a separate command called
visudofor this purpose.You CAN use any ol' text editor but visudo has built-in validation specific to the sudoers file. This is helpful because sudoers syntax is unique and arcane, and errors are potentially quite harmful.
But visudo can use any editor if you set SUDO_EDITOR or EDITOR variables. If you don't want to use vi(m) you should probably set EDITOR in your .bashrc and visudo and probably other programs will use your editor of choice.
