Display path of file in status bar

Question

GNU Emacs 23.1.1

I am wondering is there a way to display the path of the file in the status bar, instead of just the filename.

I have to open many files in many

Answer 1

This one works well for me for setting the full path in the frame:

(setq frame-title-format
  '(:eval
    (if buffer-file-name
        (replace-regexp-in-string
         "\\\\" "/"
         (replace-regexp-in-string
          (regexp-quote (getenv "HOME")) "~"
          (convert-standard-filename buffer-file-name)))
      (buffer-name))))
