I'm running tmux 1.6 and I'm trying to configure it to use vi-style keybindings as well as use the system clipboard when copying in interactive mode:

set-window-option -g mode-keys vi

bind-key -t vi-copy 'v' begin-selection
bind-key -t vi-copy 'y' "copy-selection && run \"tmux save-buffer | xclip -selection clipboard\""

Simply put, I'd like to be able to do C+[ and then use v to begin selecting text for copying, then when y is pushed, copy the selection to the tmux selection and then export it to the system clipboard using xclip.

Unfortunately, when I try to do this, I see the following:

.tmux.conf: 14: unknown command: copy-selection && run "tmux save-buffer | xclip -selection clipboard"

Is there a way to do this in tmux configuration?


This was also answered here, but it took me a while to understand how to use it, so I'll explain for anyone else that was confused.

This is basically the setting you're going for:

(for tmux versions <2.5)

bind -t vi-copy y copy-pipe 'xclip -in -selection clipboard'

(for tmux versions >=2.5)

bind -T copy-mode-vi y send-keys -X copy-pipe-and-cancel 'xclip -in -selection clipboard'

Then hit Ctrl+b [ to enter copy mode. Then hit Space followed by whatever vi movement keys to make a selection. Then, instead of hitting Enter, hit y and the selection will be copied to the clipboard.

Note: this assumes you're using tmux's default bindings with vi keys.

Tmux has different key binding tables for different modes. So, bind-key -t vi-copy y sets the action for the y key in copy mode. Initially, I was confused because I was used to hitting Enter after making a selection. Enter is actually just the default key binding for the copy-selection command (when in copy mode). The copy-pipe command allows us to bind a new key to pipe the selection to a command, which in this case is xclip.

You can see all key bindings for copy mode by running list-keys -t vi-copy.

  • Thanks so much, I had to download and compile tmux 1.9a, but it wasn't so difficult and now it just works™! – Naftuli Kay May 21 '14 at 17:02

    If it doesn't work just double check that xclip is actually installed in your system (it's not installed by default on Ubuntu, you need to sudo apt-get install xclip to get it) – ecerulm May 28 '15 at 11:26

    For OSX, replace xclip with pbcopy. For Cygwin on Windows, replace it with putclip (from the cygutils-extra package). – SnoringFrog Jun 17 '16 at 15:09

    The following binding from this blog entry works great too on Tmux 2.6 and doesn't have the downside of putting seemingly random characters on the screen when copying: bind -T copy-mode-vi Enter send-keys -X copy-pipe-and-cancel "xclip -i -f -selection primary | xclip -i -selection clipboard" – Matthias Braun Nov 30 '17 at 19:30
  • This was not working for me until I removed this line from .tmux.conf: set -g mouse on. This is supposed to enable "mouse mode" but even after removing it everything regarding my mouse works fine (scroll wheel works, mouse selection works)... – ndemou Jun 15 '18 at 10:32

The updated version to Ben Davis answer

compatible with tmux 2.4

bind -T copy-mode-vi y send -X copy-pipe "xclip -selection c"

    I find it works a bit better with copy-pipe-and-cancel rather than copy-pipe. This is on tmux 2.5 – wreckgar23 Jul 22 '17 at 23:02

You are running into a couple of technical issues:
The “special mode” bindings (e.g. vi-copy) …

  1. use a different set of commands (i.e. run-shell a.k.a. run is not available), and
  2. do not have the ability to bind multiple commands (which can normally be separated by ;—the shell’s && command separator is not available).

tmux 1.8 has copy-pipe, which could help though:

bind-key -t vi-copy y copy-pipe 'xclip -selection clipboard >/dev/null'

(There is a binding like this listed in the FAQ.)

    I have tmux 1.8 and this doesn't seem to work. (edit) Ugh, I hate textarea inputs that submit on Enter. Anyway, I added this key binding, but when I do <prefix>-y, and hit [space], the contents are not copied to the clipboard. – Ben Davis May 20 '14 at 16:04
  • Just figured it out. I didn't understand how the "vi-copy" keybinding table worked. – Ben Davis May 20 '14 at 19:28

Take a look at the tmux-yank plugin for tmux. https://github.com/tmux-plugins/tmux-yank

It provides an automated way to copy/paste from tmux to the system clipboard. It works on OSX/Linux/Cygwin systems.

  • This worked great for me, thanks for the link! – Bryan Henry Jul 31 '17 at 20:58

For macOS you can add this line to .tmux.conf

bind -t vi-copy y copy-pipe 'pbcopy'


This is what ended up working for me using tmux 2.2 and having installed xclip. For Vim style copying add the following to .tmux.conf

bind Escape copy-mode
bind -t vi-copy 'v' begin-selection
bind -t vi-copy 'y' copy-selection
# Vim style copy to clipboard
bind-key -t vi-copy y copy-pipe "xclip -selection c > /dev/null"
bind-key p run "xclip -o -sel clip | tmux load-buffer - ; tmux paste-buffer"

Here when in copy-mode PREFIX v starts the selection and PREFIX y copies to the clipboard. PREFIX p can be used to paste in the terminal.
