I'd tried using iTerm2 beta Build 1.0.0.20120724 and using bind C-y run-shell "reattach-to-user-namespace -l zsh -c 'tmux show-buffer | pbcopy'" in .tmux.conf but none works.

The solutions I found aren't specific about the system and conditions. Hence I hope the problem statement here is clear ie. Copying text from remote to OS X clipboard via iTerm2 with Tmux.

Problem:

  1. Copy text output from cat of a log file that's longer than a screen.

  2. Copy text from vertically* split screen (left and right panes) without copying the text from the other pane.
    *not sure if it should be called vertically or horizontally split.

  3. Copy text through Vim that's longer than a screen.

I'm aware of holding alt while clicking and drag to select the text. But the problem arises when you need to scroll, or are working in more than 1 pane.

  • When you say "remote", do you mean you are running tmux on the remote side of an ssh connection?

  • @chepner yes, you're right.

  • automizu's answer may be exactly what you need, but I'll refer you to my own answer on unix stackexchange. In addition to that, you would probably want tmux's save-buffer command.

This app might solve your problem, clipper.

I came across this software sometime earlier, but I have never used it. It has a screencast and it seems just to fit your need exactly.

JIC, in some cases it'd be enough to just run command through SSH and copy result with pbcopy, like this:

ssh yourhost.net 'ls /' | pbcopy

    With some cases he probably means where you have a direct connection the the target machine and are able to reverse ssh the pbcopy command. In that scenario this works.

This answer from stackoverflow may be the simplest answer. If you hold the option key, you can select and copy text in iTerm2 even if it is from a remote session running tmux.
