Try exiftool (which is written in perl):

usage:

exiftool -all= image.jpg

Answer 2

jhead can be used to delete metadata from JPG files. The following command line options to jhead are available (quoting the man page for jhead below):

   -dc    Delete comment field from the JPEG header.  Note that the comment is not part of the Exif header.
   -de    Delete the Exif header entirely.  Leaves other metadata sections intact.
   -di    Delete the IPTC section, if present.  Leaves other metadata sections intact.
   -dx    Delete the XMP section, if present.  Leaves other metadata sections intact.
