# Copy to clipboard from Tmux in El Capitan

I am quite happy with the Terminal changes in El Capitan (see e.g. this question).

However, i can't figure out how to enable copying to system clipboard from within Tmux. For instance, now that I am able to select text within Tmux properly by mouse, how can i copy selected text to clipboard as well, in addition to Tmux's own buffer?

I have the following in my tmux.conf:

setw -g mode-mouse on
set -g mouse-select-pane on
set -g mouse-resize-pane on
set -g mouse-select-window on

setw -g mode-keys vi
bind-key -t vi-copy 'v' begin-selection
bind-key -t vi-copy 'y' copy-selection


I tried modifying the last line to

bind-key -t vi-copy 'y' copy-selection \; copy-pipe "pbcopy"


but it didn't really work. Would be grateful for suggestions!

Thanks!

• Cmd-C doesn't work? – nohillside Oct 2 '15 at 9:04
• @partix - no, as copied text is auto-deselected after releasing the mouse button (or trackpad). Of course it does work in Terminal, but not from Tmux within terminal. – siphiuel Oct 2 '15 at 9:21
• Update to Tmux 2.1 broke mouse scrolling in Tmux panes. – siphiuel Oct 19 '15 at 17:35

Actually, I just find out very simple solution how to enable copying using Cmd+C again.

In default Terminal application go to View->"Allow mouse reporting" and uncheck it. Thats it.

PS: Obviously, the new nice features like dragging split screen in tmux stop working after unchecking the mouse reporting.

• PS: I used previously solution from @siphiuel, which works also fine. – Oplatek Oct 28 '15 at 3:46
• Thank you!!! This is the simplest way! Only that the history is broken.I can only see part of hitstory – Sato Mar 24 '16 at 23:54
• Super nice. This works – ShikharDua Jan 30 '17 at 18:59
• and this also works for a remote tmux session; I'm thinking that the bind-key ... copy-pipe solution might only work if it's a local tmux session. Then again, maybe if you do the remote tmux session within a local tmux session, it might work? Anyway, unchecking "Allow mouse reporting" worked for me, and there's even a shortcut ⌘-R (Cmd-R) so that you can quickly toggle it off to make a copy, then back on again. – Aaron Wallentine Mar 9 '17 at 21:30
• Thanks for the ⌘-R (Cmd-R) shortcut - that helps a lot! – haavee Mar 30 at 16:33

If you use iTerm2 3.x, you can make copy / paste work by enabling Applications in terminal may access clipboard:

Just highlight text with your mouse to copy it into the OS X clipboard!

You can also paste from the OS X clipboard into tmux with the usual Cmd + V.

• this was the easiest solution for me. – alternated direction Feb 23 '17 at 18:23
• This is awesome! – mljrg Dec 12 '17 at 11:52

If you hold the function key down you can select and copy to clipboard with apple+c as well.

• @Allan This is a complete answer, even though it's just a single line. It's that simple. – pkuhar Apr 18 '19 at 16:27
• btw, I found it only works on the laptop keyboard, not attached keyboards :( – amohr Apr 21 '19 at 6:27
• Simple and effective -- thanks! – Alessandro Mulloni Feb 19 at 9:24

Actually, i was wrong when stating that copy-pipe does not work. It does, and copy-selection is then superfluous, as copy-pipe both copies text to Tmux pasteboard and pipes to an arbitrary shell command. So the following line works:

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


However, one needs to press y before releasing the mouse button. I've stumbled across this in the documentation for tmux-yank plugin:

"When making a selection using tmux mode-mouse on or mode-mouse copy-mode, you cannot rely on the default 'release mouse after selection to copy' behavior. Instead, press y before releasing mouse."

So it works, but with somewhat annoying need to press y in order to copy mouse-selected text.

• If you are using Terminal.app: in macOS Sierra this won't work due to regression in the Terminal.app behaviour. You will need to use "reattach-to-user-namespace" hack again. – m1keil Sep 25 '16 at 3:15
• Agree on @m1keil comment. Moreover, for some reason i had to compile reattach-to-user-namespace with additional switches, like this: brew install reattach-to-user-namespace --with-wrap-pbcopy-and-pbpaste (i am using Homebrew) – siphiuel Sep 26 '16 at 11:28

Using tmux version 2.2 or later add the following to your tmux.conf file:

bind-key -t emacs-copy MouseDragEnd1Pane copy-pipe "pbcopy"
bind-key -t vi-copy MouseDragEnd1Pane copy-pipe "pbcopy"

• Works for El Capitan 10.11, tmux 2.7 – Homer Jun 16 '18 at 5:05

The answer of @Oplatek take effect

In default Terminal application go to View->"Allow mouse reporting" and uncheck it.

But by this way, we would not be able to scroll the screen by mouse.

Here's another way without disable Allow mouse reporting:

Press Fn and select the text by mouse. It keeps the selection there so you can right click and select copy.

Using tmux 2.2, OS X El Capitan, Terminal Version 2.6.1 (the default that ships with El Capitan), the following setup works flawless (so far).

\$ cat ~/.tmux.conf
set -g mouse on
bind-key -t emacs-copy MouseDragEnd1Pane copy-pipe "pbcopy"
bind-key -t vi-copy MouseDragEnd1Pane copy-pipe "pbcopy"


To copy, press the left mouse button, mark the text, and let go. The marked text is then in the clipboard and can be pasted with Cmd + v as usual.

brew install reattach-to-user-namespace


Then add to .tmux.conf:

set-option -g default-command "reattach-to-user-namespace -l zsh"


i find only one way

open terminal settings/profiles in terminal info change terminal type from xterm-256 to ansi open new terminal window and enjoy :)
