Can anyone help me set up this configuration?

If I create a new pane, the new pane should start out in the same working directory as the pane I was just in. If I create a new window, the new window should start out in the home directory (or any other global default path).

Is this possible with tmux 1.8?

Add -c "#{pane_current_path}" to the new-window/split-window commands.

Example configuration using the default key bindings:

bind  c  new-window      -c "#{pane_current_path}"
bind  %  split-window -h -c "#{pane_current_path}"
bind '"' split-window -v -c "#{pane_current_path}"

I found the pane_current_path trick here. It's also documented in upstream CHANGES.

    For me, $PWD does not work, but #{pane_current_path} works. – Henry Hu Nov 07 '15 at 04:11
  • I don't think this answers the OP's question, because he asked whether it was possible to have new windows start in the home directory. Based on this answer and the ones considered duplicates, I thought placing `bind c new-window -c "$HOME"` would work, but new windows are still created in the `pane_current_path` – cbcoutinho Mar 24 '18 at 23:09

    If you want to override `"` you have to escape the double quote like this: `bind '"' split-window -v -c "#{pane_current_path}"`. Hopefully saves someone some time. – jchook May 07 '20 at 00:07

    I should add that the characters c,|,- after "bind" represent the keys used to create new panes. By default these are c,%,". – Peaceful Feb 11 '23 at 07:45
  • Since this was the first tmux config I modified, just wanted to say that after you add this to config, run `tmux source ~/.tmux.conf` – redOctober13 Aug 22 '23 at 19:03

While @mmoya's answer works for tmux version 1.9 and beyond, the -c option for new-window is not present in earlier versions. For earlier versions, this requires a bit of mucking with default-path. Here is how I have it set up in my .tmux.conf file.

set -g default-path "~"
bind % set default-path "" \; split-window -h \; set -u default-path
bind '"' set default-path "" \; split-window -v \; set -u default-path

This makes the new-window command use the global default-path. However, when splitting a window into panes, it makes a local default-path to override it.
