stib<p>This is why I am glad I know how to use the command line: I have ~ fifty thousand stop-motion images that have been copied off camera SD cards. The camera numbers them from 00001 to 09999 and then wraps around (I don't know why it doesn't use the last digit), and the cards were taken out of the camera and copied into separate folders on a HD, but because the camera has two slots, sometimes the cards were not transferred in sequential order, so card 3 might be older than card 4.<br>So I have a bunch of photos in semi-sequential order, with many duplicate file names. And each one is about 25Mb in Sony ARW format.<br>There is a brilliant command line program called <a href="https://aus.social/tags/ExifTool" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExifTool</span></a> that can just grab the exif metadata from the image. This is waaay faster than opening it for viewing. I can use it to grab the CreateDate metadata which tells me when the photo was taken, and use another command line tool `sed` to format it into an appropriate file name. <br>So I can use the command line to traverse through all the folders, get the exif info of each ARW file and copy the image to a new directory where it will be renamed according to its creation time, and thus sorted into order.<br>And in the meantime I can post on social media.</p>
