Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

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).

Alternatives

There is 1 alternative - 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.

What others think

Use it with http://www.commandlinefu.com/commands/view/3688/smart-renaming

Comment by vnkatesh 361 weeks and 5 days ago

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

Comment by cfajohnson 361 weeks and 4 days ago

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}"' -- {} \;

Comment by sorpigal 361 weeks and 1 day ago

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!

Comment by renich 361 weeks ago

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...
