Assuming there's NOTHING but images in the directories....
find [directory] -type f | xargs mogrify [mogrify options]
examples:
find ppm -name "*gif" |xargs mogrify -strip
find people -name "*jpeg" | xargs mogirfy -geometry 600x600
Now, if you have Cygwin installed on your windos computer, just fire up a
shell and the commands should be the same.
If you have spaces in the names of files, then you need to do a few things
differently...you'll need to read the man page for xargs to get the details,
but basically you need to add -print0 to the find, and -0 right after the
xargs.
If you're doing something more complex like changing all the files named .gif,
yet saved as JPEG's.... different options to xargs.
find football -name "*square.gif" |xargs -i convert \{\} jpeg:\{\}
This will maintain the filename to be the same, but the internal structure is
now a JPEG.
good luck,
brian
