Write to Exif tags

This script brings up a yad text entry box pre-populated with text found in a specific image's Exif tag, and then writes back to the same tag with changes.

You can of course use it to write to any exif tag with a text string.

#!/bin/bash tag=comment comment_text=$(exiftool -b -$tag $@) COMMENT=$(yad --form --on-top --center --text='Enter comment' --field=:TXT "$comment_text" --wrap \ --undecorated --width=400 --height=200 --separator= --borders=10 \ --button='Write':0 --button=gtk-cancel:1 ) case $? in 252) exit 0 ;; 1) exit 0 ;; 0) exiftool -m -charset utf8 -overwrite_original -$tag="$COMMENT" $@ ;; esac #------- the double quotes around $comment_text for --entry-text= are VERY important, to insert a comment with spaces. Note, single quotes don't work. # option -charset utf8 may not be that necessary  

Here's a quick script to extract all the comments from a batch of image files, so that you can paste them into Libre Writer and do some spell checking!

It prints the whole lot to a file.

#!/bin/bash for img in $@ ;do printf "$img ------- `exiftool -b -comment $img`" >>comments done  

This one appends the exif date to multiple files...

#!/bin/bash exiftool '-filename<%f_${DateTimeOriginal}.%e' -d %y%m%d-%H%M $@  

Where %f is the filename and .%e the file extension read by exiftool. Leave out the '%f_' and you have the exif date replacing the file name.


This will prefix the file names with the exif date..

#!/bash/bin exiftool '-filename<${DateTimeOriginal}_%f.%e' -d %y%m%d-%H%M $@  

This will sort files with exif data into folders.

#!/bin/bash exiftool -r "-directory<datetimeoriginal" -d "%y-%m-%d" *.{jpg,JPG}  

This will sort any files into folders.

#!/bin/bash for i in $(ls -1 *); do DAT=$(date -r $i +%y-%m-%d); mkdir -p $DAT; mv $i $DAT ; done
