Opening a new tmux window in the current directory
If you are using tmux, you know about splitting windows and opening new windows. I do that all the time to get a new terminal to do things like run a dependency service or tail a log. Until recently, this involved having the terminal open in the initial directory where the session was started and then having to navigate to the directory of the project where I am working.
Well, it turns out that tmux supports opening a window where the terminal's directory
is the same as the directory of the current pane and it's easy to do! Simply use
the -c option to set the working directory and the {pane_current_path} variable to use
the current panes path for the value.
For example, to open a new terminal in a vertical split:
split-window -c '#{pane_current_path}'
I've configured my ~/.tmux.conf
file to change the split-window and new-window aliases to use this because I almost always want this
behavior.
# In ~/.tmux.conf
# Note that the binding to `"` needs to be escaped.
bind '"' split-window -c '#{pane_current_path}'
bind % split-window -h -c '#{pane_current_path}'
bind c new-window -c '#{pane_current_path}'
Remember, if you change your tmux configuration and want to reload the current server to use the configuration run the following command:
source-file ~/.tmux.conf
