Exif data provides a interesting insight to how and possibly where a photo was taken, however sometimes you may want to remove the data embedded in your jpg files.
I will be using two lightweight console programs:
exif – Displays the exif data using a console
mogrify – Amongst other things, strips exif data (part of imagemagick package)
Shown below is a screen dump of exif in action. The command to show machine readable exif information is ‘exif -m picture.jpg’
Now use mogrify to strip the tags ‘mogrify -strip *.jpg’
Note: morgrify will overwrite/append all files, which is what we want most of the time.
A retest with exif, shows the tags are gone!
