Rename .JPG to .jpg recursively

This command is useful for renaming a clipart, pic gallery or your photo collection. It will only change the big caps to small ones (on the extension).


There are 2 alternatives - vote for the best!

Terminal - Alternatives
find /path/to/images -name '*.JPG' -exec bash -c 'mv "$1" "${1/%.JPG/.jpg}"' -- {} \;

Recursively rename .JPG to .jpg using standard find and mv. It's generally better to use a standard tool if doing so is not much more difficult.

Know a better way?

If you can do better, submit your command here.

The rename command is not standard, and there are at least two difference versions, with different syntax.

Why use some arcane rename command when mv will do just as well?

find /path/to/images -name '*.JPG' -exec bash -c 'mv "$1" "${1/.JPG/.jpg}"' -- {} \;

well, rename is pretty useful. I tried this version in debian and fedora and it worked fine.

I agree; the implementation is not the same but, still, it works!

Hmm, if we can use the special "rename" command then how about the command "JPG2jpg". It's not very standard but it does the job with just one command...
