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.

Why is copy and paste so difficult for Linux to solve? (lemmy.world)

It seems like for at least a decade every application/framework has had their own paste buffer, and honestly I'm surprised this isn't "just working" out of the box by now.

Open Terminal
Run pwgen, double click one of the passwords.
Middle click in Terminal, the copied password pastes just fine.
Switch back to Chrome, CTRL-V into the password field.
Realize 5 minutes later when you can't login with the user you've just created, it's because the content you pasted into the password field was an URL you copied in Chrome 15 minutes ago.

And don't even get me started on vim/neovim having yet another copy/paste buffer.

Linux running X11 has 2 clipboards:

oldschool ( from terminal-only era ) => copy by selecting text (mostly in terminals) and paste using middle mouse click
more modern new style ( based on graphical interfaces ) => copy by ctrl+c (or ctrl+shift+c in terminals and such) and paste ctrl+v (ctrl+shift+v in terminals ...)

Normally both those clipboards work independent as they are handled by 2 different processes, so you can for example copy one text using ctrl+c and copy another text by only selecting second text, then you can paste both, one with middle click, second with ctrl+v

More and more distro have a clipboard managers that have a feature to "sync" both clipboards, but it's a lot of time disabled because it's more confusing people and sometimes annoying. Why it's confusing and disabled by default? Imagine that you selected some text, then did a ctrl+c, you move to some word document, select text, remove it, and want to Paste it. Guess what, the selecting you did to remove text did copy the selection to clipboard overriding what you did have there from ctrl+c.

Most if not all terminal emulators (konsole, gnome-terminal, xterm) support both clipboard styles, old-school select to copy, and new one but because the "ctrl+c" shortcut reserved to stop/interrupt applications they all decide to use ctrl+shift+c to do a copy. And yes, not only terminal emulators use ctrl+shift+c, I did have few encounters on some random apps, but most of the time, if ctrl+c is used for something else, ctrl+shift+c was available.

A very comprehensive and complete reply. I did know about the different clip buffers but reading this was still so good because no one was actually explaining it. Thanks
