Howto Convert RAW Imanges to JPG/JPEG on Linux
May 13, 2010 1 Comment1. Install ufraw . On a ubuntu machine run the following command in a treminal,
sudo apt-get install ufraw
2. cd to the directory which has raw images to be converted
3. Run the following command which will recursively traverse the directories underneath, find a RAW image with extension .CR2 and convert it into a .jpg image.
find . -type f -name *.CR2 -exec ufraw-batch –out-type=jpeg ‘{}’ \;
How To's, Misc

I normally use ufraw (0.16) without the find command:
ufraw-batch –out-type=jpeg –compression=100 –overwrite *.CR2
which would convert all cr2-files into jpegs with no compression and overwrite existing files without prompting.
