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.

Isn't ctrl-m the "enter" equivalent?
Yes. So is Ctrl+J actually. Ctrl+J corresponds to line feed (LF) and Ctrl+M corresponds to carriage return (CR) ASCII characters. They are typically treated the same way.
Found it in the classic The UNIX Programming Environment from 1984:
But then, this is for return, which technically isn't "enter", but nowadays they are sort of interpreted the same by programs?
Yeah, it’s a bit philosophical.
bind -x '"\C-j":"echo a"'in bash and Ctrl+J will do something different.sttyoptions which can change that though.
