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.

TIL GNU/linux has 2 clipboards (lemdro.id)

Pretty sure most of you already know this but for those who don't: you have two clipboards in Linux. One is the traditional clipboard where you copy with control c and paste with control v. The other one is when you highlight text and use the mouse middle click to paste text.

Ironically neither GNU nor Linux has a clipboard (well GNU Emacs probably has like 37 of them for some reason). "Primary selection" (the other clipboard that people don't tell you about) started off on X11, which of course had to implement by XFree86, which became Xorg, and then it copied (ha ha) by other non-X-related software like gpm and toolkits like GTK when using Wayland.

Emacs's regular clipboard is the "kill ring" which also allows you to retrieve any previously cut/copied text. It also has "registers" where you can store and retrieve snippets of text, which can be considered clipboards when used for this purpose. Registers can be referenced by any character you can type on your keyboard, including control characters like ^D.

This totals... a lot of clipboards.
