oscclip is a utility which utilizes the system clipboard via OSC52 escape sequences. Using these sequences, the system clipboard is accessible via SSH as well. Terminal multiplexers, such as tmux and screen are supported.

$ make

Setting the clipboard

$ echo "Foo" | osc-copy

Setting the clipboard and bypass terminal multiplexers

$ echo "Foo" | osc-copy --bypass

Reading the clipboard

$ osc-paste
Foo

• alacritty
• foot

For a list of terminals that support OSC52, see this table.

There is a bug in tmux Due to this osc-paste does not work with tmux < 3.3 running in foot.

In order to make --bypass work, allow-passthrough must be enabled. Check the manpage of tmux. osc-copy issues a warning to stderr when this option is not set and --bypass is present.

In order to let tmux set the system clipboard, the option set-clipboard must be enabled.
