tmux create new window on current directory
When you start a new window or split pane on tmux, it always start with the directory from where you run tmux command.
I prefer it start with current working directory of active tmux window. To do this, edit file
vi ~/.tmux.conf
Add
bind c new-window -c "#{pane_current_path}" bind '"' split-window -c "#{pane_current_path}" bind % split-window -h -c "#{pane_current_path}"
