Batch resizing animated gifs

How do I batch resize animated gifs with imagemagick? I have this script which works for single images but I must specify both the exact image name.

convert {path to image with filename}.gif -coalesce -resize 200x200 \
        -layers optimize-frame {output name}.gif

mogrify -path seems to batch process but animations all come out broken with mogrify.

You don't say if you are using OS X, Linux or Windows, but if on either of the first two and using bash, you can use a loop:

for f in CurrentLocation/*.gif; do convert "$f" -coalesce -resize... -layers... NewLocation/$(basename "$f"); done

If you are unfortunate enough to have to use Windows, it will look something like this:

FOR %%G IN (SOMEWHERE/*.GIF) DO convert "%%G" -set filename:new "%f" -coalesce -resize... -layers... "elsewhere/%[filename:new]"
