The command mogrify -format jpg *.NEF when run in a directory converts all *.NEF files to JPEGs. What I want to do is to be able to run mogrify in *.NEF files inside subdirectories as well using one command. I am trying to run something like: 

find . -type d exec mogrify -format jpg *.NEF \;

and of course it is not working. Can someone suggest the proper command?

It looks like mogrify from ImageMagick 6.9.9.19 writes the result in the same directory as the input file, so you can use this command:

find . -name '*.NEF' -exec mogrify -format jpg {} +

Explanation:

  • -name '*.NEF' finds all *.NEF files; use -iname if you want the search to be case insensitive.

  • -exec ... {} + executes the command on all the matching files. An alternative would be to combine find with xargs.
