Re: Question on frame title

[Benny Sum]

ls is just as an example.  I want to do unix command to get the revision 
control of a file.  Ultimately, here is what I want to do:

Say unix command:
> info_data filename
-> revision number of the file from the database

(setq frame-title-format
 (list (format "%s" (shell-command-to-string(concat "info-data " " %b "))))) 

So, I just use ls -1 as an example of unix command.

But the problem is that it seems I don't have filename correctly.  It says I 
can't access the filename.  Did you try the command and see if that works for 
you?
