Is is possible to open a new-window with its working directory set to the one I am currently in. I am using zsh, if it matters.
Create new-window with current directory in tmux
tmux;terminal multiplexer
Starting in tmux 1.9 the default-path option was removed, so you need to use the -c option with new-window, and split-window (e.g. by rebinding the c, , and % bindings to include-c '#{pane_current_path}'). See some of the other answers to this question for details.A relevant feature landed in the tmux SVN trunk in early February 2012. In tmux builds that include this code, tmux key bindings that invoke new-window will create new a window with the same current working directory as the current panes active processes (as long as the default-path session option is empty; it is by default). The same is true for the pane created by the split-window command when it is invoked via a binding.This uses special platform-specific code, so only certain OSes are supported at this time: Darwin (OS X), FreeBSD, Linux, OpenBSD, and Solaris.This should be available in the next release of tmux (1.7?).With tmux 1.4, I usually just usetmux newwin a shell that already has the desired current working directory.If, however, I anticipate needing to create many windows with the same current working directory (or I want to be able to start them with the usual <prefix>c key binding), then I set the default-path session option viatmux set-option default-path $PWDin a shell that already has the desired current working directory (though you could obviously do it from any directory and just specify the value instead).If default-path is set to a non-empty value, its value will be used instead of inheriting the current working directory from command-line invocations of tmux neww.The tmux FAQ has an entry titled How can I open a new window in the same directory as the current window? that describes another approach; it is a bit convoluted though.
