ImageMagick mogrify doesn't work

This works:

convert开发者_如何转开发 005_R.JPG -fuzz 20% -fill white -opaque "#eceaeb" 005_R_magic.JPG

.. but this doesn't:

mogrify * -fuzz 20% -fill white -opaque "#eceaeb"

what am I doing wrong here?

Thanks!

Put the file names to process at the end:

mogrify -fuzz 20% -fill white -opaque "#eceaeb" *
