Have a look at the program called 'convert':

man convert

I'm not familiar with it, but it does what you want I think. I think it's part of the ImageMagick set of tools.

Quick bash mini-script to do bulk conversion
 
I use 'convert' with a simple bash for loop quite a bit to do various tasks.

Code:
for i in *.jpg ;
do
    convert $i `basename .jpg $i`.gif
done
You can also use this trick to, for example, make thumbnails

Code:
for i in *.jpg ;
do
  convert -size 640x480 $i `basename .jpg $i`-small.jpg
done

Really? Bulk conversion? How does that work?

thanks everyone. actually i am not so good in programming because i used to do everything in windows. i am new to linux.

let say if i have several number (more than 100) of .bmp file and i want to convert it to .jpeg and those .jpeg file will be named like .bmp name. for example if the .bmp name is picme.bmp, then after the conversion, the name is picme.jpeg.
could somebody give me the script to do that?
