[X-Unix] What unix command ?

[Ken Rossman]

Here is yet another way to do a mass rename (I do this all the time),  
using
built-in features of the default unix shell under Mac OS X -- bash:

   $ for i in *eml..txt; do echo $i; mv $i $i{%%eml..txt}.txt; done

See the man pages for an explanation of '##' and '%%' shell variable
modifiers.  These are quite useful.

By the way, the above might be more politely written in a multi-line  
format
in a separate script file, but writing it in the above fashion, all  
on one
line, with semicolons for line separators, makes it easy for me to  
command-
line-edit the program if I goofed it up the first few times.  I can just
recall the command, edit, and re-execute it (I use the emacs-mode  
editing,
but vi-mode editing is also available).
