Changing image names using EXIF tool
Changing image names using EXIF tool
exiftool and a way to rename your pictures into something sensible
ExifTool is probably your best start: <http://www.sno.phy.queensu.ca/~phil/exiftool/>
I second exiftool. Lots of options to rename files. If you rename files
based on createtime and perhaps other fields like resolution you will
end up with unique filenames and then you can filter the duplicates Here
is a quick command which will rename every file in a directory according
to createDate
exiftool "-FileNameCreateDate" -d "%Y%m%d_%H%M%S.%%e" DIR
If the files were all captured with the same device it is probably super
easy since the exif info will be consistent. If the files are from lots
of different sources…good luck.
#!/bin/sh OUTF=rem-duplicates.sh; echo "#! /bin/sh" > $OUTF; find "$@" -type f -print0 | xargs -0 -n1 md5sum | sort --key=1,32 | uniq -w 32 -d --all-repeated=separate | sed -r 's/^[0-9a-f]*( )*//;s/([^a-zA-Z0-9./_-])/\\\1/g;s/(.+)/#rm \1/' >> $OUTF; chmod a+x $OUTF; ls -l $OUTF
It should be straightforward to change “md5sum” to some other key –
e.g. EXIF Date + some other EXIF fields. (Also, isn’t this really a
question for superuser.com or similar?) Same thing, but faster… You
md5sum everyfile, but you only need to do it for files with the same
size:
#/bin/bash find "$@" -type f -not -empty -printf "%-32i%-32s%p\n" \ | sort -n -r \ | uniq -w32 \ | cut -b33- \ | uniq -D -w32 \ | cut -b33- \ | xargs -0 -d"\n" -l1 md5sum \ | uniq --all-repeated=separate -w32 \ | cut -b35-
