=== usage
  * renames 'foo.lis' to 'foo.txt', 'my.old.stuff.lis' to 'my.old.stuff.txt':<code bash>zmv '(*).lis' '$1.txt'</code>
  * Something simpler (for basic commands) is the -W option<code bash> zmv -W '*.lis' '*.txt'</code>
  * If you combine this with noglob, you don't even need to quote the arguments.<code bash>alias mmv='noglob zmv -W'
mmv *.c.orig orig/*.c</code>

=== the code whisperer
<code bash>zmv 'Page(*)/shot.jpg' 'shot-${1}.jpg'</code>
