I'm trying to set my tmux window's title to be the current directory that I am in. Now pane_current_path is perfect for this, but it prints the full path in my machine.
Is it possible to run pane_current_path though some formatting and only print out the current directory?
Currently using it like this
setw -g window-status-current-format "#{pane_current_path}" setw -g window-status-format "#{pane_current_path}" Tmux man page, under FORMATS section says:
The
b:andd:prefixes are basename(3) and dirname(3) of the variable respectively.
Following option should effectively change window's title to basename of current directory:
setw -g automatic-rename-format "#{b:pane_current_path}"
(Inspired by https://stackoverflow.com/a/32426739 and https://stackoverflow.com/a/9757133)
This can be done if your shell has a 'precmd' hook (bash and zsh do); this hook would be setting tmux's pane title via escape sequence, and you'd use #{pane_title} instead of #{pane_current_path}. For bash, add something like this to ~/.bashrc:
[[ -n "$TMUX" ]] && PROMPT_COMMAND='echo -n -e "\e]2;${PWD##*/}\e\\"'
