This post discusses tmux, a terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be run simultaneously in a single window.
Other uses include executing remote commands in a session on a server through an SSH connection, disconnecting, and later returning to the session to see the command output.

Tmux is a rewrite of GNU Screen.

First thing is first- add this to your ~/.tmux.conf

setw -g mode-keys vi
set -g history-limit 10000

# Enable OSC 52 clipboard support
set -s set-clipboard on

# Optional: Allow applications (like vim) to use the clipboard
set -as terminal-features ',xterm-256color:clipboard'

# Use 'Enter' to yank in vi-mode (modern tmux 2.4+)
bind-key -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel

# bind-key -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel 'xclip -se c -i' # old linux
# bind-key -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel 'pbcopy' # old mac

This relies on OSC52 support, which is terminal dependent. This works with iTerm2 but not MacOS default terminal.

printf "\033]52;c;$(printf 'Hello OSC52' | base64)\a"

After running that, your clipboard should contain the contents Hello OSC52.
