I have been searching for a simple way to copy loads of text from remote servers for a while.
This includes files, but is sometimes also only multiple lines from stdout of a program. Oftentimes this is kinda hard to do in terminal emulators, so I wrote a very small program to copy text via Operating System Commands.
This allows the terminal emulator itself to copy the text directly into the host clipboard. No x11 pass-through needed.
Lots of text editors like vim (with oscyank-plugin) or helix already have a functionality like that, but opening large files just to copy them is stupid (also not all servers I admin have the oscyank or helix even installed).
If you want to know, if your terminal emulator supports osc52, please refer to the oscyank-repo, they have a nice list.
