Title: Use tag value as filename when extracting data
Post by: v16p20 on November 18, 2020, 03:23:57 PM

Hi,

is it possible to use the value of a tag as filename when extracting data?

In my case I want to extract the RAW embedded in DNG [-OriginalRawImage] and name it with the original filename [-OriginalRawFileName]

exiftool -b -OriginalRawImage -w temp file.dng

So I woud like to change "temp" to something like "-filename<OriginalRawFileName".

Thanks

This could be done in two steps:

1. exiftool -p "exiftool -b -originalrawimage $directory/$filename -W $directory/$originalrawfilename" -ext dng DIR > out.bat

2. out.bat

(assuming you're running from Windows cmd.exe)

Thank you Phil. Your solution works perfect. Exiftool never disappoints.

Here's an addition: to extract the RAW with the current name of the DNG and the extension of OriginalRawFileName I used

exiftool -p "exiftool -b -originalrawimage $directory/$filename -W $directory/${filename;s/(.+?)(\.[^.]*$|$)/$1/}.${originalrawfilename;s/.*\.([^.]*)/$1/}" -ext dng DIR > out.bat

Or is there any other solution?
