Remove EXIF info from JPG file under Linux

Install the package:

sudo apt-get install libimage-exiftool-perl

And use the application, e.g. to remove EXIF metadata from several files at once:

exiftool -all= your-files-*.jpg 

The original files are written as *.jpg.original. You can also write the metadata to a text file:

exiftool myphoto.jpg > myphoto.exif
