Set up tmux
Install it:
sudo apt install tmux
Add this to your ~/.bashrc (or ~/.zshrc if you use zsh):
if [[ -z $TMUX ]]; then
tmux
fi
This automatically starts tmux when you open a terminal.
Note: If you use powerlevel10k, set this code before the instant prompt preamble.
Tmux buffer to clipbaord
To automatically copy tmux buffer to clipboard, add this to your ~/.tmux.conf:
bind -T copy-mode-vi y send-keys -X copy-pipe-and-cancel "xclip -selection clipboard -i"
bind -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel "xclip -selection clipboard -i"
This bind y (for vi mode) and Enter to copy the tmux buffer to clipboard. After settings this, run tmux source-file ~/.tmux.conf.
Enable vi mode
Tmux uses the Emac style by default. To change this to vi:
setw -g mode-keys vi
Enable mouse support
If you prefer mouse support, add this:
set -g mouse on
bind -T copy-mode-vi MouseDragEnd1Pane send -X copy-pipe-and-cancel "xclip -selection clipboard -i"
