Remove meta information of JPG files in Linux

To remove, edit and manipulate meta data inside JPG en-masse`, you can use a tool called exiftool. Since this is a perl module you can either install it through CPAN, or in an easier way like this:

$ apt-get install libimage-exiftool-perl

To simple wipe out all the meta data from an image or multiple images (example, for security reasons):

$ exiftool -all= *.jpg
