Complete off-topic but:

1. ImageMagick has mogrify tool, with that everything is simpler::

	mogrify -format jpg -sampling-factor 1x1 -quality 90 *.png

2. Even with shell way (mogrify can only put output files in the same
   directory) you don't have to play with backticks, just
   convert command::

	convert $a ${a%.png}.jpg
