Identifying jpegs without extension and recursively moving/renaming

[darinhouston]

I'm trying to use EXIFTOOL to recover photos from an old iPhone backup.

The idea is to recursively dig through folder structure of iPhone backup files (renamed without extensions) to identify jpegs and copy them to a common folder while adding a .jpg extension. 

Nothing I do seems to work.

Try something like
exiftool -ext * -if "$FileTypeExtension eq 'jpg'" "-Directory</path/to/new/directory/%f.$FileTypeExtension" -r /iphone/backup/

Because the files don't have extensions, you need to use -ext (extension) option with an asterisk to process all files.  Since you only want the jpgs, the -if option checks to make sure it's a jpg.  It will then copy to the new directory, keeping the original name (the %f) and adding the extension (see the Extra tags page).  The -r (recurse) option will recurse though all subdirectories.

If you're on Mac/Linux, swap the double/single quotes and make sure you're using regular quotes, not fancy quotes.

Thanks, but it's not working.

Check your quotes.  On Mac/Linux, single quotes on the outside of an argument, double quotes inside.  Try this, copy/paste if need be
-if '$FileTypeExtension eq "jpg" '
Take note that then quotes around jpg are double quotes ", not two single quotes ''

-if '$FileTypeExtension eq "jpg" '

On Mac/Linux you need also to escape the asterisk in the extension switch: -ext "*" otherwise the shell is replacing the asterisk with all matching filenames in the current directory.

Thanks, good catch, but no cigar.

Took a while to recurse, then nothing was in the present directory when done. 

Just to confirm... here's the first of the folders...  There are at least a couple of jpegs there.

Ok, try this instead
exiftool -ext '*' -if '$FileType=~/JPEG/i' '-Directory<./%f.$FileTypeExtension' -r /Volumes/homes/maxwell/Backup/b2e0e152dcb6b9dafcbb9c0d051f054ea78bba0f/

Copy/paste it.  Don't add an asterisk to the end.

[darinhouston]

Interesting. Not sure why using a regex made such a difference.  But, it did move things. 

But, still not quite the desired outcome, though a step in the right direction.  It created a directory for each file and appended .jpg to the directory name and copied the photo into that directory without the extension.  I would like a single folder with all of these image files with .jpg appended to the file name.  The file name can stay the same or just be a sequential IMG_000x.jpg sort of naming.

Oops, my fault.  Don't know how I got that into my head.  Change Directory into FileName.
exiftool -ext '*' -if '$FileType=~/JPEG/i' '-FileName<./%f.$FileTypeExtension' -r /Volumes/homes/maxwell/Backup/b2e0e152dcb6b9dafcbb9c0d051f054ea78bba0f/
