I have a Media Temple (dv) server which I am setting Magento up on.

I have uploaded a few thousand images to the /media/import directory that the client has provided me with. The problem is, some images are .jpg and others are .JPG.

Is there a way of batch renaming them on the server? I really don't want to have to do it locally and the re-upload them all.

I would ideally make them all lowercase so that they are uniform with the other image naming schemes used by Magento.

Thanks,

Danny

A bash suggestion:

   for file in *.JPG; do newfile=`echo $file|sed 's/.JPG$/.jpg/'` ; mv -i "$file" "$newfile" ; done

It loops over all the files with a .JPG extension, and for each of them it uses sed to construct the new filename by turning a terminal .JPG into a terminal .jpg, and performs the mv. The -i is just in case you have a fred.JPG and a fred.jpg already. Don't forget to distinguish between single quotes and backticks, both of which are used, and aren't interchangeable.

Or use the preferred $(). Also, variables that contain filenames should always be quoted in case there are spaces in the names. – Dennis Williamson Nov 12 '10 at 15:15
Dennis is absolutely right, I should have thought of that, and have modified the above accordingly. On the other hand, filenames with spaces are an aberration and should be avoided anyway! (opinion! opinion!) – MadHatter Nov 12 '10 at 16:26
Should I just run this from within the directory using Terminal? – dannymcc Nov 12 '10 at 20:43
@dannymcc: Yes. MadHatter: Photographs and music are two of the file types that one should expect to spaces in their names. – Dennis Williamson Nov 12 '10 at 22:33
Worked a treat, thanks! – dannymcc Nov 12 '10 at 23:07

If you have the utility called rename installed (it's a Perl script) you can do:

rename 'y/A-Z/a-z/' *
